The electrons of an atom store nuclear energy.

A hollow aluminum cylinder 19.0 cm deep has an internal capacity of 2.000 L at 23.0°C. It is completely filled with turpentine at 23.0°C. The turpentine and the aluminum cylinder are then slowly warmed together to 91.0°C.

A fixed resistor, (R) is in parallel with a variable resistor; both are connected to a real battery (internal resistance is not negligible). A) Originally the fixed and variable resistors have the same resistance.

A 535 kg roller coaster car began at rest at the top of a 93.0 m hill. Now it is at the top of the first loop-de-loop. This roller coaster's track is nearly frictionless, so resistance can be ignored. Using g = 9.
