Ethyl alcohol is in a 310 mm-diameter tank at an initial height of 2 m. The ethyl alcohol exits the tank through a sharp-edged orifice, which has a diameter of 2 mm and located at the bottom of the tank. The tank is open to the atmosphere. What is the approximate actual velocity in m/s coming out of the orifice at ethyl alcohol height of 1 m

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.
