Two hikers start from the top of the same hill but take different paths to the bottom. Hiker A weighs more than hiker B. The hikers take the paths shown in the figure. Hiker B takes a long time to descend than hiker A. Which of the following is a correct statement about the change in gravitational potential energy ΔUA for the Earth-hiker A system and the change in gravitational potential energy ΔUB for the Earth-hiker B system? ΔUA=ΔUB, because the height descended for both is the same. ΔUA⁢=ΔUB, because the height descended for both is the same. A ΔUA ΔUB, because the time required for hiker A to descend the hill is shorter. ΔUA⁢>ΔUB, because the time required for hiker A to descend the hill is shorter. D ΔUA>ΔUB, because the gravitational force exerted on hiker A is greater.

this is an example of "committed" time.

committed time, as contracted time, takes need over essential and available time since it is seen as profitable work. it alludes to the time allotted to keep up a home and family. at the point when a man is commuting using committed time this individual may feel that the drive is an obligation to family, for example, strolling youngsters to class or driving a mate to work. contracted and committed time clients may feel that their commute could really compare to the commute of important or leisure time clients on the grounds that their commute is profitable work. in this manner, they might be more disposed to pick a mechanized method of movement.
