My answers are incorrect The weight of bodies may change somewhat from one location to another as a result of the variation of the gravitational acceleration gwith elevation. Accounting for this variation using the relation g = a- bz where a = 9.807 m/s² and b=3.32 × 10-6 s-², determine theweight of a(n) 80-kg person at sea level (z = 0), in Denver (z = 1610 m), and on the top of Mount Everest (z = 8848 m).The weight of the person at sea level isThe weight of the person in Denver is882.63 N.88221 N.The weight of the person on the top of Mount Everest is8801 N.

Answered: The weight of bodies may change…
