The answer is D) The outcome of the experiment will be non observable
The magnitude of the ball's displacement when the ball is rolled uphill with a 5 meters before it slows, stops and begins to roll back and the ball rolls downhill 9 meters before coming to rest is 4 meter. Just subtract 9 meters with 5 meters. Therefore the answer is 4 meters.
Answer: 300 turns
Explanation: In order to explain this problem we have to consider the relationship between the voltage for the primiry and secondary and the turns for their coils.
This expression is consequence of the Faraday law because the magnetic flux is the same for both coils then the induced emf are the same for both circuits.
They are reñated as follow:
Vs=Vp*Ns/Np where Vs and Vp are the voltage for the secondary and primary coil, respectively.
Ns and Np are the turns for the secondary and primary coil, respectively.
Then we have:
Ns=Vs*Np/Vp= 16*2250/120=300
