Answer:
The answer to your question is A. Hope this helped
The answer is B i just took the test and got it correct!
Answer:
1.8 MJ
Explanation:
PE = mgh
PE = (1500 kg) (3.7 N/kg) (324 m)
PE = 1,798,200 J
PE = 1.8 MJ
The force needed to do the work is equal to 25 N. The power of the machine doing the work is equal to 250 W.
The power can be explained as the speed of doing work or work done in unit time. The SI unit of measurement of power joules per second (J/s) Watt (W).
Power can be defined as a time-based parameter and the change at work is done upon an object. The mathematical formula for power can be represented as mentioned below.
Power = Work/ time
P = W/t
Given, the work done by the machine, W = 2500 J
The distance moved by the object, d - 100 m
The work done can be represented in the form of the equation:
W = F.d
2500 = F.100
F = 25 N
The power of the machine doing the work, P = W/t
P = 2500 / 10
P = 250 W
Therefore, the force required to do the work is equal to 25 N. The power of the small machine doing the work is equal to 250 W.
