Gina examines the equations for electric power and ohm's law. she thinks that there is a third equation that can calculate power using only voltage and resistance. which statement best evaluates gina’s idea? it is correct, because i = . it is correct, because i = . it is incorrect, because both equations for power use current. it is incorrect, because ohm’s law does not include i2.

Abag of potato chips contains 2.00 l of air when it is sealed at sea level at a pressure of 1.00 atm and a temperature of 20.0 deg c. what will be the volume of the air in the bag if you take it with you, still sealed, to the mountains where the temperature is 7.00 deg c and atmospheric pressure is 70.0 kpa? assume that the bag behaves like a balloon and that the air in the bag is in thermal equilibrium with the outside air.
