A 1.50-F capacitor is connected to a 12.0-V battery for a long time, and then is disconnected.

Question:

A 1.50-F capacitor is connected to a 12.0-V battery for a long time, and then is disconnected. The capacitor briefly runs a 1.00-W toy motor for 2.00 s. After this time,
(a) by how much has the energy stored in the capacitor decreased?
(b) What is the voltage across the plates?
(c) How much charge is stored on the capacitor?
(d) How much longer could the capacitor run the motor, assuming the motor ran at full power until the end?
