If a 240 volt voltage source is connected to a wire with 10

ohms of resistance, what is the current?

Answers

Answer 1

If a 240 volt voltage source is connected to a wire with 10 ohms of resistance, then the current is 24 amp.

Given data as per the question is:

Voltage given - 240 V

Resistance = 10 ohm

The formula to be used in such numerical is,

V=IR --------------------- (A)

where V in the equation is the voltage, I in the equation is the current and R in the equation is the resistance.

Substituting the values in the equation (A)

240=I(10)

I= 240/10 = 24 amp

The current is 24 amp.

The formula V=IR is the ohm's law.  The current which is flowing through the wire is directly proportional to the potential difference applied across its ends of it ,provided that the temperature and all the other physical conditions of the wire like stresses and strains remains absolutly constant.

A snowboarder stands at the edge of a 4.50 m high half-pipe. The mass of the snowboarder is 55.0 kg. What is the gravitational potential energy of the snowboarder?

Answers

Answer:

he gravitational potential energy of the snowboarder is 2532.5 J.

Explanation:

The gravitational potential energy of an object is given by the formula:

PE = mgh

where m is the mass of the object, g is the acceleration due to gravity, and h is the height of the object.

In this case, the mass of the snowboarder is 55.0 kg, the acceleration due to gravity is 9.8 m/s^2, and the height of the snowboarder is 4.50 m. So, the gravitational potential energy of the snowboarder can be calculated as:

PE = (55.0 kg)(9.8 m/s^2)(4.50 m) = 2532.5 J

So, the gravitational potential energy of the snowboarder is 2532.5 J.

Answer:

2425.5 J

Explanation:

The gravitational potential energy of an object can be calculated using the formula:

PE = m * g * h

where PE is the potential energy, m is the mass of the object, g is the acceleration due to gravity (9.8 m/s^2 on the surface of the Earth), and h is the height of the object above a reference point.

Plugging in the values, we get:

PE = 55.0 kg * 9.8 m/s^2 * 4.50 m = 2425.5 J

So the gravitational potential energy of the snowboarder is 2425.5 J (joules).

how much work is done when a hoist lifts a 200-kg rock to a height of 3 m? (use 9.8 m/s2 for the acceleration due to gravity.)

Answers

The work done by the hoist to lift the 200-kg rock to a height of 3 meters is 5880 joules, assuming an acceleration due to gravity of 9.8 m/s^2 and no angle between the force and direction of motion.

What is acceleration due to gravity?

Acceleration due to gravity is a physical constant that describes the acceleration experienced by objects near the Earth's surface due to the force of gravity. The acceleration due to gravity is denoted by the symbol "g" and has a numerical value of approximately 9.8 meters per second squared (m/s^2) at sea level. This means that if an object is dropped from a height of, say, 10 meters, it will accelerate towards the Earth's surface at a rate of approximately 9.8 m/s^2. The acceleration due to gravity is a vector quantity, which means it has both magnitude and direction. Its direction is always towards the center of the Earth.

The work done by the hoist to lift the rock can be calculated using the formula:

Work = force x distance x cos(theta)

where force is the upward force exerted by the hoist on the rock, distance is the vertical distance lifted, and theta is the angle between the force and the direction of motion.

In this case, the force is equal to the weight of the rock, which is given by:

force = mass x acceleration due to gravity

= 200 kg x 9.8 m/s^2 = 1960 N

The distance lifted is 3 meters, and the angle between the force and the direction of motion is 0 degrees, since the force is directly upward and the motion is also upward.

Therefore, the work done by the hoist is:

Work = 1960 N x 3 m x cos(0) = 5880 J

So the hoist does 5880 joules of work to lift the 200-kg rock to a height of 3 meters.

a constant friction force of 30 n acts on a 60 kg skier for 20 s. what is the skier's change in velocity?

Answers

The skier's change in velocity is 10 m/s.

To calculate the change in velocity of the skier, we can use the equation for average force:

F = m * a

where F is the force, m is the mass, and a is the acceleration. We can rearrange this equation to solve for the acceleration:

a = F / m

We can then use the equation for average acceleration:

a = (vf - vi) / t

where vf is the final velocity, vi is the initial velocity, and t is the time. We can rearrange this equation to solve for the change in velocity:

vf - vi = a * t

Substituting the known values into these equations, we get:

a = F / m = 30 N / 60 kg = 0.5 m/s²

vf - vi = a * t = 0.5 m/s² * 20 s = 10 m/s

Therefore, the skier's change in velocity is 10 m/s. Note that the direction of the change in velocity is opposite to the direction of the friction force.

Explain the applications of Newton’s law of motion to the concept of displacement, velocity and acceleration​

Answers

Answer:

Newton's laws of motion describe the relationship between the motion of an object and the forces acting on it. These laws can be applied to the concepts of displacement, velocity, and acceleration as follows:

-First Law: The law of inertia

This law states that an object will remain at rest or in uniform motion in a straight line unless acted upon by an external force. This law implies that if there is no net force acting on an object, the object will remain at rest or in uniform motion in a straight line. In terms of displacement, this law means that an object's displacement will not change unless acted upon by an external force. In terms of velocity, an object's velocity will remain constant unless acted upon by an external force. In terms of acceleration, an object's acceleration will be zero unless acted upon by an external force.

-Second Law: The law of force and acceleration

This law states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. In terms of displacement, this law means that the displacement of an object is directly proportional to the force acting on it. In terms of velocity, this law means that the change in velocity of an object is directly proportional to the force acting on it. In terms of acceleration, this law means that the acceleration of an object is directly proportional to the force acting on it and inversely proportional to its mass.

-Third Law: The law of action and reaction

This law states that for every action, there is an equal and opposite reaction. In terms of displacement, this law means that if an object exerts a force on another object, the other object will exert an equal and opposite force on the first object, resulting in a displacement. In terms of velocity, this law means that if an object exerts a force on another object, the other object will exert an equal and opposite force on the first object, resulting in a change in velocity. In terms of acceleration, this law means that if an object exerts a force on another object, the other object will exert an equal and opposite force on the first object, resulting in a change in acceleration.

In summary, Newton's laws of motion have numerous applications to the concepts of displacement, velocity, and acceleration. These laws can help us understand how objects move and how they respond to external forces. They are essential for fields such as physics, engineering, and astronomy, where the motion of objects is of critical importance.

Explanation:

Newton’s First Law of Motion

“An object at rest will stay at rest, and an object in motion will stay in motion unless acted on by a net external force"

This means that motion cannot change or decrease without the effect of an unbalanced force. If nothing happens to you, you will never go anywhere. If you’re going in a certain direction, unless something happens to you, you’ll always go that way forever.

That is, if the resultant force (the vector sum of the forces acting on the body) is zero, then the velocity of the object is constant. When we say that the velocity of an object is constant, we mean that both magnitude and direction are constant.

Examples

The electric fan continues to move for a period after the electricity is turned off.

Fall back forward when the stationary bus starts to move.

Newton’s Second Law of Motion

“If a force affects an object, the object gains acceleration, proportional to its strength and inversely proportional to its mass.”

Newton’s second law studies the movement of an object when external forces affect it. When a constant force affects a huge object, it causes it to accelerate, that is, to change its speed, at a constant rate.

In the simplest case, the force acting on an object at rest causes it to accelerate in the direction of the force. However, if the object is indeed in motion it may appear that the object is speeding up, slowing down, or changing its direction depending on the direction of force, directions taken by the object, and the frame of reference in which it is moving Relative to each other.

This relationship applies the principle of preserving the momentum, which is that when the sum of the resultant forces acting on the object is equal to zero, the momentum of the object remains constant. The resultant force is equal to the rate of change in the momentum.

This law also means that when two equal forces act on two different bodies, the object with greater mass will have less acceleration and slower motion, and the object with less mass has greater acceleration. For example, to illustrate:

If we have two similar engines, one for a large car and the other for a small car, then the small one will have more acceleration because its mass is less and the large one will have less acceleration because its mass is greater.

Newton’s Third Law of Motion

“For every action, there is an equal and opposite reaction.”

All forces in the universe occur in equal but oppositely directed pairs. There are no isolated forces; for every external force that acts on an object there is a force of equal magnitude but opposite direction which acts back on the object which exerted that external force.

In the case of internal forces, a force on one part of a system will be countered by a reaction force on another part of the system so that an isolated system cannot by any means exert a net force on the system as a whole. A system cannot “bootstrap” itself into motion with purely internal forces, to achieve a net force and an acceleration, it must interact with an object external to itself.

Engineers apply Newton’s third law when designing rockets and other devices, for example, the rush of gases from the rocket to the top when it ignites causes it to increase its speed.

When a person walks it affects the earth strongly and the earth also strongly affects it so both the earth and the person affect each other.

When you jump, your feet apply force to the ground, and the earth applies an equal and opposite reaction force that pushes you into the air.

When a person is in water, the water pushes the person forward while the person pushes the water back, both affect each other.

What is a steam turbine generator?

A device that turns steam into energy is called a steam turbine generator. A generator and a steam turbine are its two major parts.

The steam turbine is an apparatus that turns a group of blades attached to a shaft using high-pressure steam. The steam expands as it moves over the blades, speeding up the shaft's rotation. The steam is then recycled for future use after being condensed back into liquid form.

An apparatus that transforms mechanical energy into electrical energy is a generator. The generator's rotor, which rotates inside a group of stationary coils while the steam turbine's revolving shaft connects to it, produces an electromagnetic field that generates an electrical current.

The energy conversion efficiency of a steam turbine generator can reach up to 50%, which is substantially higher than that of an incandescent light bulb or a car engine. Around 10% of the energy used by incandescent light bulbs is converted into visible light, with the remaining energy being wasted as heat. The average energy conversion efficiency of an automobile engine is roughly 25%, which means that only 25% of the fuel's energy is turned into usable work and the remaining 75% is lost as heat.

"If a meteor with a 20 m in diameter impacts Earth on land, approximately the crater is 200-400 m in diameter." Correct option is A.

A meteor is a small rock or piece of debris that travels through space and enters the Earth's atmosphere. When a meteor enters the Earth's atmosphere, it encounters friction and heat due to the atmospheric resistance, causing it to ignite and create a bright trail or shooting star in the sky. If a meteor is able to reach the surface of the Earth, it is called a meteorite.

When a meteor strikes a planet, there will almost certainly be a hole made at the site of impact. As the item moves more quickly, gets bigger, or is heavier, the crater will grow bigger. The meteor's mass and velocity are the best indicators of the magnitude of the impact crater.

The size of the crater created by a meteorite impact depends on many factors, such as the composition of the meteorite and the density of the material that it impacts. A crater with a dimension of 200–400 metres would be produced by a meteorite with a 20 m diameter.

When a person stands on the ground, their weight is exerted on the Earth's surface, and the surface responds by exerting an equal and opposite force on the person's body. This force is commonly referred to as the normal force. It is important to note that the normal force is perpendicular to the surface and is not the same as the force of friction, which is parallel to the surface and opposes motion.

questions: 1. if you want to measure voltage across on a resistor connected to a 5v dc power supply, which two jacks of the dmm should be used? where do you set the function/range knob? which voltage range should be selected? 2. if the current flowing in a circuit is about 60ma. where should the function/range knob be set at in order to measure the current? which two jacks of the dmm will be used? what range should be used?

Answers

The voltage range should be selected to be at least 5V or greater to ensure accurate measurement and with the DMM placed in series with the circuit.

To measure the voltage across a resistor connected to a 5V DC power supply, you should use the red and black jacks of the DMM, where the red jack is connected to the positive side of the resistor and the blackjack is connected to the negative side. The function/range knob should be set to measure DC voltage (V~), and the voltage range should be selected to be at least 5V or greater to ensure accurate measurement.

If the current flowing in a circuit is about 60mA, the function/range knob should be set to measure DC current (A) and the range should be selected to be at least 200mA or greater to ensure accurate measurement. The two jacks of the DMM used, in this case, will be the red and black jacks, where the red jack is connected to the positive side of the circuit and the blackjack is connected to the negative side, with the DMM placed in series with the circuit.

in this example, if the emf of the 4 v battery is increased to 17 v and the rest of the circuit remains the same, what is the potential difference vab ?

Answers

The potential difference Vab remains unchanged. Since the potential difference across the 4V battery is now 17V, the potential difference across the 12V battery is still 12V.  The potential difference is still 4V.

Given the initial emf of circuit (V1) =4V

The battery is increased to (V2) = 17V

According to the Kirchhoff loop rule, the total current flowing into and out of a junction must equal one another. In other words, the sum is equal to zero. Using equation 1 and the Kirchhoff loop rule, we can calculate Vab (the voltage across ab) when the external magnetic field is 12 volts.

+12 - (I x 2) -(I x 3)-(I x 4)-(4)-(I x 7) = 0

I = 8/16 = 0.5 A

Vab = 4V + (I x 7) + (I x 4)

Vab = 4V + (0.5 x 7) + (0.5 x 4) = 4 +3.5+2 = 9.5 V

Using equation 1 and the Kirchhoff loop rule, we can calculate Vab (the voltage across ab) when the external magnetic field is 17 volts.

+17 - (I x 4) -(I x 3)-(I x 2)-(12)-(I x 7) = 0

I = 5/16 = 0.3125A

Vab = 17V -(I x 7) - (I x 4)

Vab = 17 - ( 0.3125 x 4)-(0.3125  x 7) = 17 - 1.25 - 2.1875 = 13.5625V

How do electronegativity values help us determine the charge?

Answers

Electrons in a polar covalent bond are moved towards the more electronegative atom; consequently, the atom with the partial negative charge is the more electronegative atom. The bigger the electronegativity difference, the more polarized the electron distribution and the larger the atoms' partial charges.

The electronegativities of the elements can be used to forecast the sort of bond that will form between two elements. Large variances in electronegativity produce ionic bonds, whereas lesser differences produce covalent bonds. A formal charge and electronegativity criterion can be used to assess the relative contribution of non-equivalent resonance structures. Negative formal charge should preferentially dwell on more electronegative atoms, whereas positive formal charge is more easily carried by fewer electronegative atoms. The capacity of an atom to attract shared electrons in a covalent connection is referred to as electronegativity. The greater the electronegativity value, the more strongly that element draws the shared electrons.

an object is found to be moving in a circle with a constant speed. is there a force acting on the particle? if so, in what direction is this force. if not, why not? explain your reasoning.

Answers

Because the object's motion is moving in the same direction as the velocity vector, the velocity vector is also pointed in a tangent direction to the circle.

While it moves in a circle, an object constantly changes its direction. The path of the object is always perpendicular to the circle. Given that its direction matches the motion of the item, the velocity vector is also oriented tangent to the circle. While it moves in a circle, an object constantly changes its direction.
