A57-kg mountain climber, starting from rest, climbs a vertical distance of 712 m. at the top, she is again at rest. in the process, her body generates 4.3 × 106 j of energy via metabolic processes. in fact, her body acts like a heat engine, the efficiency of which is given by equation 15.11 as e = |w|/|qh|, where |w| is the magnitude of the work she does and |qh| is the magnitude of the input heat. find her efficiency as a heat engine.

glen is correct.

step-by-step explanation:

glen is correct because when you multiply 4 * 2 = 8.

and 4 * 3 = 12.

this is an example of "committed" time.
