How much force did the gymnast use to climb the rope?
Answer:
2,500,000 MJ (
)
Explanation:
According to the work-energy theorem:
The work done on an object is equal to the amount of energy transferred
In this problem, the energy transferred by the rocket is

Therefore, the work done must be equal to the energy transferred, therefore:

Answer:
A thin wire has more resistance than a thick wire
A short wire has less resistance than a long wire
A warm wire has more resistance than a cool wire
When its tangential speed is constant
