Do mass depends on velocity?.

The law of gravitation is allegedly called the Newton's 4th law. This law gave the world a breakthrough in understanding the universe in a better way.

Newton's law of gravitation states that every object attracts every other object in the universe with a force, called gravitational force. This force is directly proportional to the product of the masses of both the object and inversely proportional to the square of the distance between them. Mathematically it is described as:

F = GmM/R²

Where, F is the gravitational force, G is the universal gravitational constant, M & m are the masses of the objects and R is the distance between the objects.

Torque is calculated using the following formula: Torque = (3*EMF2)/ (4*pi*Synchronous Speed*Reactance). When the rotor rotates at its fastest speed, the maximum running torque occurs.

It achieves mathematical equivalence between rotor reactance per phase and rotor resistance per phase. Torque is spelled with the letter T. This scenario is conceivable if the value of the denominator shown below equals zero. The maximum torque is thus produced when, while the motor is running, the rotor reactance per phase is equal to the rotor resistance per phase. When the value of sX 20 = R 2 is entered, equation (1) is transformed into the equation for maximum torque. The rotor's stationary reactance and maximum torque are inversely connected.

Answer:

2.9s

The moving charge from point A to point B, the electric force that has done work is 2.08 J.

The work done by the electric force exchanges with the amount of charge transferred and exchanges with the potential difference between the starting and destination points.

To complete the task, we must find out the potentials at nodes A and B. Then we can calculate the electric potential energy of the charge Q 3 in these places. The work done by the electric force by moving the charge from A to B is equal to the difference in the electric potential energy.

To answer this question, we use the following formula:

W = Q3 (Q1-Q2)/4πε₀ (1/a - 1/b)

Numerical substitution:

Q3 = -3. 1 μC = -3.1 x 10⁻⁶C

Q1 = -5.6 μC = -5.6 x 10⁻⁶C

Q2 = 3.4 μC = 3.4 x 10⁻⁶C

a = 3 cm = 3 x 10⁻² m

b = 4 cm = 4 x 10⁻² m

ε₀ = 8.85 x 10 ⁻¹² C²N⁻¹m⁻² (from the table)

W = Q3 (Q1-Q2)/4πε₀ (1/a - 1/b)

W = -3.1 x 10⁻⁶C (-5.6 x 10⁻⁶C - 3.4 x 10⁻⁶C)/4π8.85 x 10 ⁻¹² (1/0.03 - 1/0.04)

W = -3.1 x 10⁻⁶C (-9 x10⁻⁶C)/4π8.85 x 10 ⁻¹² (1/0.03 - 1/0.04)

W = 27.9 x 10⁻¹² C/4π8.85 x 10⁻¹² (8,3)

W = 27.9 x 10⁻¹² C/111,25 x 10⁻¹² (8,3)

W = 0,25 x 8,3

W = 2.08 J

Thus, moving the charge from point A to point B, the electric force that has done work is 2.08 J.

Calculate the inverse tangent of the ratio of the displacement components in the y and x directions to determine the direction of the displacement vector. The magnitude of displacement is equal to the distance covered in a given interval of time if the particle moves at a constant or variable velocity in the same direction, because if it changes direction, the magnitude of displacement changes and does not remain equal to the distance covered.

A quantity with magnitude and direction must also follow certain combination rules in order to qualify as a vector. Vector addition, denoted symbolically as A + B = C, is one of these (vectors are conventionally written as boldface letters). Geometrically, the vector sum can be visualized by placing the tail of vector B at the head of vector A and drawing vector C so that it completes the triangle (starting from the tail of A and ending at the head of B). If A, B, and C are vectors, then it must be possible to reverse the operation and achieve the same result (C), B + A = C.

Self-ignition, also known as pre-ignition, occurs in an internal combustion engine when the fuel-air mixture in the combustion chamber ignites before the spark plug fires.

One way to avoid pre-ignition is to limit the compression ratio of the engine, as a higher compression ratio can lead to higher temperatures in the combustion chamber.

The ideal gas law states that PV = nRT, where P is the pressure, V is the volume, n is the number of moles, R is the ideal gas constant, and T is the temperature.

The compression ratio of an engine is the ratio of the volume of the combustion chamber when the piston is at the bottom of its stroke (the "swept volume") to the volume of the combustion chamber when the piston is at the top of its stroke (the "clearance volume").

Given that the temperature at which self-ignition would occur using a certain brand of petrol is 350°C, and assuming that the ideal gas law applies, we can calculate the highest compression ratio that may be used to avoid pre-ignition.

To do this, we need to know the initial temperature and pressure in the combustion chamber, as well as the final temperature and pressure after compression. We can then use the ideal gas law to calculate the compression ratio.

In conclusion, based on the information provided, it is possible to calculate the highest compression ratio that may be used to avoid pre-ignition in an engine using the ideal gas law. However, more specific information such as the initial temperature and pressure and the specific brand of petrol is needed for a more accurate calculation.

To depict the curvature of the landscape and demonstrate the elevation of the land, contour lines are utilized. The flow direction of a river can also be shown using contour lines. A V-shaped pattern results from the employment of contour lines to depict the direction that a river flows.

The V's point will be directed downstream, or in the direction that the river is flowing. Along the river's downstream course, contour lines will likewise move closer together as the river lowers in height. Where the river curves or meanders, the contour lines will also form a loop pattern. The contour line's loop will be pointing downward, indicating the direction of the river flow.

Mass does not depend on density. Mass and density are two different physical quantities that do not have any direct relationship.

Mass is a scalar quantity that measures the amount of matter in an object and is independent of its location or motion. It is the total amount of matter in an object, and it doesn't change when the object is compressed or expanded.

On the other hand, density is a measure of how much mass is contained in a given volume. It is defined as the ratio of the mass of an object to its volume. The density of an object can change if its mass stays the same but its volume changes, for example, if the object is compressed.

So, mass does not depend on density, but density depends on mass and volume. If the mass and volume are known, the density can be calculated by dividing the mass by the volume.

The time it takes for the sandbag to reach the ground would depend on the height from which it was released.

To find out how long it takes for the sandbag to reach the ground, we can use the equation of motion for a vertically falling object under the influence of gravity:

s = v0*t + (1/2)gt^2

where s is the distance fallen, v0 is the initial velocity (which is 0 m/s for the sandbag), t is the time elapsed, and g is the acceleration due to gravity (approximately 9.8 m/s^2).

We know that the sandbag is being released from the balloon and has an upward acceleration of g/4. So, the equation of motion becomes

s = v0t + (1/2)(g - g/4)*t^2

We also know that s is the distance fallen to the ground, which we can take as the final distance.

Now solving the equation for t

t = sqrt(2*s/(g-g/4))

It is given that the magnitude of the upward acceleration is g/4, so (g-g/4) = 3g/4, so the final equation becomes

The power of a hairdryer with a current of 4A and a resistance of 60Ω is 240W (watts).

Resistance is the opposition to the flow of electric current or the process of slowing down the flow of electric current. It occurs when electrons collide with atoms in a conductor, such as a wire. Resistance is measured in ohms and is determined by a material's electrical properties, like its cross-sectional area, length and type. Resistance can be used to control the amount of current in a circuit. It can also be used to convert electrical energy into thermal energy.

This is calculated by multiplying the current (4A) by the voltage (V = I x R, so V = 4A x 60Ω = 240V) and then multiplying the voltage by the current (240V x 4A = 240W). The power of a hairdryer is measured in watts and is the rate at which energy is used by the appliance. The higher the wattage, the more powerful the hairdryer will be.
