What happens to matter when it changes from a solid to a liquid? O Space between particles increases and particles can then slide past each other.
O Space between particles decreases and particles remain closely packed together.
O Space between particles remains the same and only the appearance changes.

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) =_

Difference between series and parallel circuits

The amount of work done is determined by 2 factors. describe an example of work (using the scientific definition) list the 2 factors that determine the amount of work done.
