Answer:

P = 1.4 W

Step-by-step 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,


P=(W)/(t)\\\\P=(10,000)/(2* 3600)\\\\P=1.38\ W

or

P = 1.4 W

So, the power of the battery is 1.4 W.
