An 82 kg hiker climbs Mt. Humphrey near Flagstaff. During a two-hour period, the hiker’s vertical elevation increases by 540 meters. Find the power generated to increase the hiker’s PEg

The answer is b.the gaseous state is electrically positive, while the plasma state is electrically negative. 

Ibelieve the answer is d. densityhope my answer has you : )

At maximum height, kinetic energy is converted in potential energy  formula: at max height, ke = ½ * 0.27kg * (16m/s) ² = 34.56 j  so the remaining pe = (41.70 – 34.56)= 7.14 j = 0.27 kg * 9.8m/s² * h  = (9.8/7.14 * 0.27)so max height h = 5.08 or 5 m
