Answer:
Power = Energy/time
Energy = Power xtime.
Time= 20hrs
Power = 100Watt =0.1Kw
Energy = 0.1 x 20 = 2Kwhr.
This Answer is in Kilowatt-hour ...
If the one given to you is in Joules
You'd have to Change your time to seconds
Then Multiply it by the power of 100Watts.
Answer:
Velocity
Explanation:
Velocity is an object's change in motion per unit time in a specified direction
I'm warning you before i answer this i'm not guaranteeing i'm going to answer this wright but I'm pretty sure its bill pushed a car for 5 minutes for 20-km while doing 15 J of work. Why I think this is the answer is because it directly tells you the most information giving you the time it took him to move the object that distance and also telling you how many joule's of force he's exerting (power).
Hope this helped :)
Well, according to Newton’s second law of motion, the formula he had devised would be
Fnet = m • a
N = kg • m/s^2
In terms of mass and acceleration, it would be that 1 N = 1 (kg•m/s^2).
