The gas in a cylinder has a volume of 8 liters at a pressure of 109 kpa. the pressure of the gas is increased to 211 kpa. assuming the temperature remains constant, what would the new volume be?

Atoaster oven has a resistive heating element. the average rate at which it dissipates energy as thermal energy is 1.00 \(\rm kw\). in the united states, emf amplitude in household circuits is \(\mathcal e_{\max}\) = 170 \({\rm \; v}\) and the \(\rm ac\) oscillation rate is 60 \(\rm hz\). part a what is the root-mean-square current through the heating element?
