Achild tosses a ball straight up into the air. when is the ball's potential energy the greatest?

a. when it reaches the top of its flight

b. when it first leaves the child's hand

c. when it approaches the top of its flight

d. when it begins to fall back to the child's hand

A.when it reaches the top of its flight

Explanation:

This theory is base on gravitational potential energy which state that potential energy in an object increases as weight and height increases.

the amount of potential energy stored by an object depend s on the mass and height.

answer; i believe that the correct answer is ; males are hemizygous for the x chromosome;

as the gila monster consumes the eggs or young of the desert cottontail and gambel's quail, thus its main food supply is only accessible for a restricted time duration every year. however, for this, the gila monsters exhibit three adaptations, which elevate their survival rate in the desert condition.  

first, is that they possess huge bodies, and can consume greater concentrations of food during a small period. secondly, they require to feed infrequently as they can accumulate fat in their tails. ultimately, their rate of metabolism is very low, so that they can burn their reservoirs of fat gradually.
