The magnetic field created by a large current passing through plasma (ionized gas) can force current-carrying particles together. this pinch effect has been used in designing fusion reactors. it can be demonstrated by making an empty aluminum can carry a large current parallel to its axis. let r represent the radius of the can and i the current, uniformly distributed over the can's curved wall. determine the magnetic field just inside the wall.

In the circuit, the switch s has been open for a long time and r = 125 kohm. it is then suddenly closed. (a) determine the time constant before the switch is closed. s (b) determine the time constant after the switch is closed. _ s (c) let the switch be closed at t = 0. find the current in the switch as a function of time. (use t for time. express your answer in milliamps and seconds.) i(t) =_

An insulated thermos contains 148 g of water at 72.7 Ėc. you put in a 11.7 g ice cube at 0.00 Ėc to form a system of ice + original water. the specific heat of liquid water is 4190 j/kgā¢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?
