Suppose you raise this book (inertia \(m=3.4 \mathrm{~kg}\) ) from the floor to your desk, \(1.0 \mathrm{~m}\) above the floor.

(a) Does the gravitational potential energy of the Earth-book system increase or decrease?

(b) By how much?

(c) Conservation of energy requires that this change in potential energy be compensated for by a change in energy somewhere in the universe. Where?
