Because the earth rotates about its axis, a point on the equator experiences a centripetal acceleration of 0.033 7 m/s2, while a point at the poles experiences no centripetal acceleration. (a) show that at the equator the gravitational force on an object must exceed the normal force required to support the object. that is, show that the object's true weight exceeds its apparent weight. (b) what is the apparent weight at the equator and at the poles of a person having a mass of 75.0 kg

Atank has a shape of a cone with a radius at the top of 2 m and a height of 5 m. the tank also has a 1 m spout at the top of the tank. the tank is filled with water up to a height of 2 m. find the work needed to pump all the water out the top of the spout. (use 9.8 m/s2 for g and the fact that the density of water is 1000 kg/m3.)
