The distance of Venus to the sun must be: (= equal, > greater than, < less than)

< 1 A. U.
> 1 A. U.
= 1 A. U.

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

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.)

With physics question #5? for any !
