24. A 50-turn coil has a diameter of 15 cm. The coil is placed in a spatially uniform magnetic field of magnitude 0.50 T so that

the face of the coil and the magnetic field are perpendicular. Find the magnitude of the emf induced in the coil if the magnetic field is reduced to zero uniformly in (a) 0.10 s, (b) 1.0 s, and (c) 60 s.

Answer:

0.1 = 4.42v

1.0 =0.44v

60 = 7.4 × 10^-3 V

Explanation:

Apply the formula of:

Emf = (No of turns × magnetic flux)÷(the given time)

Where your magnetic flux = (0.50 × cross sectional area(pi × 0.075^2))

baherus [9]

To solve the problem we will require the concept of Force as a definition of pressure and Area, and the concept of light pressure itself determined by the relationship between intensity and the speed at which light travels. We will match the terms and find the desired force value,

F = PA

Here,

P = Pressure

A = Area

Pressure due to the light of the sun will be

P= \frac{I}{c}

Here,

I = Intensity

c = Speed velocity

Equation both therms we have that

F = \frac{IA}{c}

We have a circular area then

F = \frac{I(\pi r^2)}{c}

Replacing with our values (Adding the radius of the Earth)

F = \frac{(1.4*10^3W/m^2)(\pi (6.32*10^6m)^2)}{3.0*10^8m/s}

F = 6.0*10^8N

Therefore the Force on Earth due to radiation pressure is 6*10^8N

Manu took a pebble and a sheet of paper both weigh one gram. His friend told that if we drop both at the same time, the pebble w
Nata [24]

Answer: friction has no role to play in this case. because friction usually occurs between to parts which come in contacts. examples (a)our joints in the human body (b)two mechanical parts (shafts).

Explanation:

However what this topic relates to is gravity. The pebble and paper both weigh one gram, but have different density this is the sole reason why if both are drop from same height the pebble would reach the ground faster than the paper because it is more denser. unlike the paper with a lesser density which would take a longer time to reach the ground.

Which is not a property of light
Anestetic [448]
<span>a) light is a form of matter less dense than air
b) light travels in straight lines
c) light has different colors
d) light has different intensities and can be dim or bright

Yes, thank you for coming back and supplying the list of choices.

At the level of Physics all the way up to somewhere in college, <em>choice-a)</em>
is not a property of light.
