The fastest lap around a 2400m circular track was 34 seconds. what was the driver’s average speed?

Mechanical energy is when the amount of kinetic and potential energies added together remains the same. conserved created lost

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) =_

The energy produced as a result of this flow of electrons from atom to atom is called
