Two resistors of resistance 19 each are connected in series. A potential difference of 10 V is then applied across the resistors. What is the resulting current through the resistors?

Work out sian speed for the first 30 minutes of her journey. give your answer in km/h.

An insulated 40 ft^3 rigid tank contains air at 50 psia and 120°f. a valve connected to the tank is now opened, and air is allowed to escape until the pressure inside drops to 25 psia. the air temperature during this process is kept constant by an electric resistance heater placed in the tank. determine the electrical work done during this process.
