A car battery dies not so much because its voltage drops, but because chemical reactions increase its internal resistance. A good car battery typically has a terminal voltage of about 12.5 V and an internal resistance of about 0.020 Ω. When the battery dies its voltage can drop slightly, let's say it drops to about 10.1 V and the internal resistance increases to around 0.100 Ω. Required:
a. How much current could the good battery alone drive through the starter motor?
b. How much current is the dead battery alone able to drive through the starter motor?

Awelder using a tank of volume 7.50×10^-2 m^3 fills it with oxygen (with a molar mass of 32.0 g/mol ) at a gauge pressure of 3.30×10^5 pa and temperature of 37.1 ∘c. the tank has a small leak, and in time some of the oxygen leaks out. on a day when the temperature is 23.1 ∘c, the gauge pressure of the oxygen in the tank is 2.00×10^5 pa . a) find the initial mass of oxygen. b) find the mass of oxygen that has leaked out.
