An explosion occurs at the end of a pier. the sound reaches the other end of the pier by traveling through three media: air, fresh water, and a slender metal handrail. the speeds of sound in air, water, and the handrail are 339, 1480, and 5060 m/s, respectively. the sound travels a distance of 141 m in each medium.

(a) after the first sound arrives, how much later does the second sound arrive?
(b) after the first sound arrives, how much later does the third sound arrive?

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) =_
