a woman using a compass and a map walks 132° east of north for 6 km. find the components of the woman's displacement.

ax = 4.46 km, ay = 4.01 km

ax = 0.74 km, ay = 0.67 km

ax = 4.46 km, ay = −4.01 km

ax = 0.74 km, ay = −0.67 km

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) =_
