(5%) problem 17: a solid aluminum sphere of radius r1 = 0.105 m is charged with q1 = +4.4 μc of electric charge. it is surrounded concentrically by a spherical copper shell of inner radius r2 = 0.15 m and outer radius r3 = 0.242 m. an electric charge of q2 = -1.1 μc is placed on the copper shell. the situation is static.
(a) find the magnitude of the electric field, in newtons per coulomb, inside the aluminum ball.
(b) what is the magnitude of the electric field, in newtons per coulomb, inside the copper of the shell, i. e., at a radius r from the center such that r2 < r < r3?

Water is siphoned from a large tank and discharges into the atmosphere through a 50-mm diameter tube. the end of the tube is b = 2.1 m below the tank bottom which is a = 7.4 m deep, and viscous effects are negligible. determine the maximum height h over which the water can be siphoned without cavitation occurring. atmospheric pressure is 101.4 kpa, and the water vapor pressure is 1.79 kpa (absolute)

An insulated thermos contains 148 g of water at 72.7 ˚c. you put in a 11.7 g ice cube at 0.00 ˚c to form a system of ice + original water. the specific heat of liquid water is 4190 j/kg•k; and the heat of fusion of water is 333 kj/kg. what is the net entropy change of the system from then until the system reaches the final (equilibrium) temperature?
