(d) The circuit is connected for 300 s
The total current in the circuit stays at 0.56 A
Calculate the total charge flow.
Use the equation:
charge flow = current x time

First answer marked as brainiest which is the correct equation describing the first law of thermodynamics? a) when the internal energy of a system changes, it equals the amount of heat added plus the work done. b) when work is done by the piston, it is equal to the heat added plus the change in internal energy of the system. c) when heat is added to the system, it is equal to the amount of work done by the piston plus the change in internal energy of the system.
