With air resistance, how does increasing the mass for the same diameter cannonball affect the time, range, and height of the flight?

As shown in fig. p3.64, a closed, rigid tank fitted with a fine-wire electric resistor is filled with refrigerant 22, initially at 2108c, a quality of 80%, and a volume of 0.01 m3. a 12-volt battery provides a 5-amp current to the resistor for 5 minutes. if the final temperature of the refrigerant is 408c, determine the heat transfer, in kj, from the refrigerant.

What should the power status of a circuit be when measuring resistance with an ohmmeter?
