I think that the girl has greater tangential acceleration because she is closer to the center and the acceleration is greater there.
A. Increase power
The relationship between power, work, and time is:
Power = work / time
So power is the rate of work done. It is visible that power and time obey an inverse relationship, so if one wants to decrease the time taken with a constant amount of work, one would increase the power.
5.
explanation: the answer is 5
Yes they should all be going the same speed.
Hope this helped :)
The problem is most likely that the commutator brushes bounces as the motor shaft rotates.
