State the right hand rule of the direction of magnetic field in a conductor carrying current

How does the amount of energy required to hold each proton and neutron in the nucleus compare to the energy released when they are removed?

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) =_
