Apotter's wheel of radius 11 cm starts from rest and rotates with constant angular accel- eration until at the end of 35 s it is moving with angular velocity of 19 rad/s. what is the angular acceleration? answer in units of rad/s2.

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) =_
