Aperson is found dead at 5pm in a room whose temperature is 21°c. the temperature of the body is measured to be 25°c when found, and the heat transfer coefficient is estimated to be 8 w/m2·k. modeling the body as a 30-cm-diameter, 1.70-m-long cylinder and using the lumped system analysis as a rough approximation, estimate the number of hours that passed from the time of death of the person to the time the body was found.

The electric field between square plates of a parallel-plate capacitor has magnitude e. the potential across the plates is maintained with constant voltage by a battery as they are pulled apart to twice their original separation, which is small compared to the dimensions of the plates. the magnitude of the electric field between the plates is now equal to a)e b)e/4 c)e/2 d)4e e)2e
