Freya is investigating different types of insulators. She wraps different insulators around a metal can of hot water. At the start the water is at 90 °C. She measures the how long it takes for the temperature to reach 60 ° C.

State the type of energy transfer through the metal can
Material: Paper, Cotton, Foam, Wool
Time to drop to 60(seconds): 4,7,15,10

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) =_
