A 10,000J battery is depleted in 2h. What power consumption is this? * A) 5000W
B) 3W
C) 1.4W
D) 20000W

show your work please

P = 1.4 W

Explanation:

Given that,

The work done or the energy of the battery, E = 10,000 J

Time, t = 2 h

We need to find the power consumption. Let it is P. Power is the rate of doing work. So,

or

P = 1.4 W

So, the power of the battery is 1.4 W.

the body's situation won't change the forces are equal opposit and on the same body

probably not if net force is zero
