Answer:
2.80 MJ
Explanation:
(a) We want to calculate the energy U of the battery, where its voltage is E = 13.0V and the supplied current is I = 60 A. We can neglect the internal resistance, so the terminal voltage equals the emf of the battery V = 13.0V. The quantity of delivered energy is given by the rate at which energy is delivered to it in a certain time t. We could obtain the rate at which energy is transferred by using equation , where the rate represents the power P = IV. Therefore, the energy produced is given by
U = P*t (P = IV)
U = I*V*t (1)
Now we can plug our values for I, V and t into equation (1) to get the energy produced in time t = 1 h = 3600 s
U = I*V*t = (60 A)(13 V)(3600s) = 2.80 MJ
Around 8 hours and 20 minutes
Explanation:
I divided 500 by 60 and got 8.3333333333 and i round it up to 8.20, so it is 8 hours and 20 minutes.
Temperature is a measure of the average kinetic energy of the particles of a substance.
