A 1500kg car is placed on the large piston with a radius of 4m. a) What is the minimum upward force that the large piston must exert to lift the car?

b) If the mechanical advantage of the hydraulic lift system is 20, what is the minimum down ward force

that should be applied to lift the car?

c) What is the radius of the small piston?

d) What is the pressure exerted by the large piston? e) How far should the small piston descend in order to lift the car by 2m?​

In which of the following cases is work being done on an object? question 2 options: pulling a trailer up a hill carrying a box down a corridor suspending a heavy weight with a strong chain pushing against a locked door

When a vertical beam of light passes through a transparent medium, the rate at which its intensity i decreases is proportional to i(t), where t represents the thickness of the medium (in feet). in clear seawater, the intensity 3 feet below the surface is 25% of the initial intensity i0 of the incident beam. what is the intensity of the beam "10" feet below the surface? (give your answer in terms of i0. round any constants or coefficients to five decimal places.)
