Hi there!
To find the potential energy of the ball at B, we can use the equation:
PE = mgh
Plug the given gravity, mass, and height:
PE = (1.5)(0.5)(9.8) = 7.35 J
At A, all of this potential energy is changed to kinetic energy, so we can use the following equation:
v = √2KE/m
Plug in the solved for energy and mass:
v = √2(7.35)/1.5
Solve:
v ≈ 3.13 m/s
Answer:
Part a)
ZERO
Part b)
N = 10 turns
Explanation:
Part a)
As we know that transformer is used to change the input voltage into required output voltage
Here this input and output is considered only when it will change with time as the whole concept is based upon Faraday's law where we need to change the flux with time.
So if we have input Source is DC source then output voltage will be zero as there is no flux change
Part b)
As we know by the principle of transformer
so total number of turns in secondary coil must be 10
