The answer is a. the rotor
I'm pretty sure it's B
I hope that helps
This answer is True, but I don't think this is much help now lol
The distance from the earthquake`s focus.
Answer:
43,555 W
Explanation:
Since the speed is constant, this means that the force applied to lift the equipment is equal to the weight of the equipment. So we can write:
where
m = 1000 kg is the mass
is the acceleration due to gravity
So,
Then the work done in lifting the equipment is:
where
d = 200 m is the displacement of the equpment
Substituting,
Finally, the power used to lift the equipment is the ratio between the work done and time taken:
where
t = 45 s is the time taken
Solving,
