Many organ system serve to maintain a healthy body. the excretory system is an organ system which is composed of all sweat glands, the lungs, the rectum, and the kidneys, which all function to remove waste material. how does removing excess waste the body to maintain overall health?

a removing excess waste the body increase its internal temperature.

b removing excess waste prevents people from growing to tall.

c removing excess waste prevents to body from recycling reusable material.

d removing excess waste prevent disease and support cell function

Suppose water is leaking from a tank through a circular hole of area ah at its bottom. when water leaks through a hole, friction and contraction of the stream near the hole reduce the volume of water leaving the tank per second to cah 2gh , where c (0 < c < 1) is an empirical constant. a tank in the form of a right-circular cone standing on end, vertex down, is leaking water through a circular hole in its bottom. (assume the removed apex of the cone is of negligible height and volume.) (a) suppose the tank is 20 feet high and has radius 8 feet and the circular hole has radius 2 inches. the differential equation governing the height h in feet of water leaking from a tank after t seconds is dh dt = − 5 6h3/2 . if the height of the water is initially 8 feet, how long will it take the tank to empty? (round your answer to two decimal places.)
