An air-conditioning system is used to maintain a house at 72oF when the temperature outside is 90oF. If this air-conditioning system draws 5 hp of power when operating, determine the maximum rate of heat removal [BTU/min] from the house that it can accomplish.

What is the fate of the electrons that interact with a specimen in an electron microscope?

When using the scientist method, which step comes last?

A6.0-μf air-filled capacitor is connected across a 100-v voltage source. after the source fully charges the capacitor, the capacitor is immersed in transformer oil (of dielectric constant 4.5). how much additional charge flows from the voltage source, which remained connected during the process?
