Suppose the charge on the inner conducting sphere is +3 µC, while +4 µC of charge is deposited on the conducting shell. (a)Find the surface charge (in µC) on the inner surface of the shell.
(b)Find the surface charge (in µC) on the outer surface of the shell

What was the first instrument to ever record an earthquake?

What is the mass of the water that is being heated? it requires 2,500 joules to raise a certain amount of water (c = 4.186 jig c) from 20.0°c to 60.0°c. o 159 o 40 g o 63 g o 80 g

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?
