describe the magnetic field due to the current in two wires connected to the two terminals of a source of emf and twisted tightly around each other.

Answers

The magnetic field due to the current in two wires connected to the two terminals of a source of EMF and twisted tightly around each other is either μo I / π a or zero

The magnetic field created by a long current carrying wire is given by the formula,

B = μo I / 2 π a

B = Magnetic field

μo = Permeability constant

I = Current

a = Distance

There are two possibilities if two are twisted together.

1 ) If the current in both the wires is flowing in the same direction, the net magnetic field will be the sum of magnetic field intensity of both the wires.

B = μo I / 2 π a + μo I / 2 π a

B = 2 μo I / 2 π a

B = μo I / π a

2 ) If the current in both the wires is flowing in the opposite direction, the net magnetic field will be the difference of magnetic field intensity of both the wires.

B = μo I / 2 π a - μo I / 2 π a

B = 0

Therefore, the magnetic field due to the current in two wires connected to the two terminals of a source of EMF and twisted tightly around each other is either μo I / π a or zero

Numerical problems.
a) convert 300kelvin into the Celsius scale.
b) Convert 220° C into kelvin scale.
c) Convert 30° C into fahrenheit scale.
d) Convert 260° F into °C​

Answers

Answer:

a) 27 degree Celsius

b) 493.15K

c) 86 Fahrenheit

d) 126.667 degrees celsius

Explanation:

a) To convert from Kelvin scale to Celsius scale, subtract 273 from Kelvin scale

Hence, 300 - 273 = 27 degree celsius

b) The temperature T in Kelvin (K) is equal to the temperature T in degrees Celsius (°C) plus 273.15, that conversion formula:

T(K) = T(°C) + 273.15

hence, 220 + 273.15 = 493.15K

c) The formula to convert Celsius to Fahrenheit is °F = °C × (9/5) + 32

F = [ C × (9/5) + 32 ]

Given that, C = 30

F = 30 × (9/5) + 32

F = 54 + 32

F = 86

Thus, 30 °C is equivalent to 86 °F.

d) Formula

(260°F − 32) × 5/9 = 126.667°C

Draw a diagram of a projectile that shows what is happening to the vertical (y) velocity of a projectile as it moves along its path . You must include what is happening to the speed of the velocity on the way up the way down and the max height.

Answers

The vertical velocity of the projectile increases but reaches zero at the maximum height and begins to decrease.

What is a projectile?

When we talk of the projectile, we are talking about the object that is moving along a parabolic path. Hence the object that is undergoing the projectile motion is going to have a curved path. Take an instance, when you kick a soccer ball, you have to notice that the ball would tend to curve as it moves up in the air and then begins to descend. That is a typical example of a projectile motion.

Now, we have to note that at the maximum height, the vertical velocity of the object would be zero. When I throw an object up, the vertical velocity of the object would continue to increase until the object reaches the maximum height where the vertical velocity is zero and then the vertical velocity of the object begins to decrease as shown in the image.

Volume is a measure of the occupied three-dimensional space.

In ancient times, volume was measured using similarly shaped natural vessels, and later standardized vessels were used. The volume of some simple 3D shapes can be easily calculated using arithmetic formulas. The volume of more complex shapes can be calculated using integral calculations if there is an equation that constrains the shape. Zero-, one-, and two-dimensional objects have no volume.

What is mechanical advantage of a hydraulic lift?An illustration of Pascal's law is the hydraulic system.By exerting a modest force on the small piston, we can generate a bigger force on the large piston.At each piston, the ratios of force to area must be the same.Three practical tools that make use of Pascal's law are hydraulic brakes, lifts, and presses.

Mass of the elephant: M = 1200 kg.

Let the diameter of the piston the student is standing on is d.

and  the diameter of the piston the elephant is standing on is D.

Using Pascal's law,

Weight of the student ÷ area  of the piston the student is standing on = Weight of the elephant ÷ area  of the piston the elephant is standing on.

What is center of gravity?

The center of gravity is the average position of the weight of an object.

Given,

Given radius of wheel rim (R): 20 cm

Center of gravity 1 mm away from axis of rotation (z-axis)

This indicates imbalance on x-y plane,

Now, let's assume unbalanced weight is more towards positive x-axis, hence the center of gravity is towards positive x-direction.

In order to statically balance the mass and bring center of gravity towards z-axis, we need to place similar amount of mass 1 mm in negative x-direction.

But as we know adding huge weight to wheel is always unpreferable so we will add M amount of weight on -20 cm in x-direction.

In order to balance the weight, moment about the central axis should be zero.

His image is formed at a 0.75m distance from the mirror while the focal length and the radius of curvature are 1.00m and 2.00m respectively.

To calculate the image distance you can use the formula for the mirror's magnification which is,

                                                    [tex]\begin{aligned}\\\\M&=\frac{V}{U}\end{aligned}[/tex]

Here V and U represent the image distance and the object distance measured from the mirror's centre.Therefore,

For the second part, you can use the lens formula as you know V and U now, as follows.

Answers

Cepheid Variables stars are intrinsic variables which pulsate in a foreseeable way. In addition, a Cepheid star's phase (how often it pulsates) is directly related to its luminosity or brightness. Cepheid variable stars are good standard candles.

First, their luminosity is quite lofty (the most luminous Cepheids are 40,000 times more luminous than the Sun), so they can be noticed at large distances. Second, their luminosities can be determined from the Period-Luminosity Relation.

Through observations of Cepheid variables, astronomers have reckoned the distances to other galaxies. They compare the Cepheid variable's apparent brightness with its intrinsic brightness. The distinction between observed and actual brightness relents the distance.

Answer:

a star whose luminosity pulses at a regular rate

Explanation:

got it on quiz right

An object weighs 600N on moon
find it's mass on earth and moon
Find its weight on earth

Answers

Answer: 100N

Explanation:

Weight on earth = 600N

Let g= 10m/s^2 on earth

Mass on earth =  600/10 =60 kg

Now, since mass is a constant quantity so, it will remain 60 kg on the moon also.

Now, weight on moon = mg

m= mass =60 kg

g′ = acc. due to gravity on moon =  1/6th  the value on earth

So, Weight on moon =  1/6th  of the weight on earth

⇒ Weight on the moon =600 × 1/6​ = 100 N

Hope it helps and good luck!

qm.2 a particle has a velocity that is 90.0% the speed of light. if the wavelength of the particle is 1.5x10-15 m, calculate the mass of the particle.

Answers

If the wavelength of the particle is 1.5 x 10⁻¹⁵ m,  the mass of the particle will be 1.636 × 10⁻²⁷ kg

Velocity of the particle = 90.0% of c ( speed of light)

Wavelength of the particle (λ) = 1.5 × 10⁻¹⁵ m

Mass of the particle = ?

Calculate the velocity of the particle

    velocity = (90.0 / 100)(3 × 10⁸ m/s)

    velocity = (0.90)(3 × 10⁸ m/s)

    velocity = 2.70 × 10⁸ m/s

Now calculate the mass of the particle by using the following equation:

   λ = h / mv

Rearrange the equation for mass

    m = h / λv

value of h = 6.626 × 10⁻³⁴ Kg.m².s⁻¹

Put the values

    m = (6.626 × 10-34 Kg.m².s⁻¹) / (1.5 × 10⁻¹⁵ m)(2.70 × 10⁸ m/s)

    m = 1.636 × 10⁻²⁷ Kg

In noncyclic photophosphorylation, electrons flow in a one-way path from water to.

Answers

In noncyclic photophosphorylation, electrons flow in a one-way path from water to NADP⁺.

ADP is converted to ATP by photophosphorylation, which makes use of sunlight. Photolysis is the process by which the water molecules are divided into hydrogen and oxygen. The noncyclic photophosphorylation process uses the hill reaction, a one-way flow of electrons from water to NADP+. Non-cyclic photophosphorylation is the name given to the process of cooperative energy production.

The water molecule splitting produces a proton, which when combined with an electron transforms NDAP into NDAPH2. Thus, in noncyclic photophosphorylation, electrons go from water to NADP+ in a single direction.

Phosphorylation is a crucial process that takes place in a living cell because it produces the ATP, an energy-rich molecule. The enzymes kinases and phosphorylases are used in this process to add the phosphate group to ADP in order to create ATP.
