Alarge aquarium of height 4 m is filled with fresh water to a depth of d = 2.30 m. one wall of the aquarium consists of thick plastic with horizontal length w = 8.80 m. by how much does the total force on that wall increase if the aquarium is next filled to a depth of d = 3.30 m? (note: use g = 9.81 m/s2 and rho = 998 kg/m3.)

Most short-period comets do not have randomly oriented orbits because

Abird flies directly overhead from where you stand at an altitude of 300.0 m and at a speed horizontal to the ground of 20.0 m/s. the bird has a mass of 2.0 kg. the radius vector to the bird makes an angle \thetaθ with respect to the ground. the radius vector to the bird and its momentum vector lie in the xyxy-plane. what is the bird’s angular momentum about the point where you are standing?
