To lift a car, you use a hydraulic lift filled with a fluid that has density of 1 1200 kg/m3. the radius of one half of the lift is 0.5 meters and the diameter of the other half of the lift is 2.5 meters. before you put a mas of 200 kg on the smaller piston, the heights of each piston are the same. if the car weighs 2200 kg, how high will it be raised?

For which pair of objects would adding the same a

An charge with mass m and charge q is emitted from the origin, (x, y)=(0,0). a large, flat screen is located at x=l. there is a target on the screen at y position y(h), where y(h) > 0. in this problem, you will examine two different ways that the charge might hit the target. ignore gravity in this problem. 1.assume that the charge is emitted with velocity v(0) in the positive x direction. between the origin and the screen, the charge travels through a constant electric field pointing in the positive y direction. what should the magnitude e of the electric field be if the charge is to hit the target on the screen? express your answer in terms of m, q, y(h), v(0), and l. 2.now assume that the charge is emitted with velocity v(0) in the positive y direction. between the origin and the screen, the charge travels through a constant electric field pointing in the positive x direction. what should the magnitude e of the electric field be if the charge is to hit the target on the screen? express your answer in terms of m, q, y(h), v(0), and l.
