A) W is positive, Q is negative

Explanation:

Upon stretching the rubber band we are doing work on it, so the work done is positive as the energy is transferred to the rubber band. When The skin detects the increment in temperature it's because of the heat leaving the rubber band so Q is negative.

since you're a real machine, your ama is always less than your ima, because you can never totally eliminate friction.
