A of current flows through a wire where 100 V of voltage (potential difference) was measured across it. What is the resistance of the wire? Remember to show all your working out.

Give your answer a unit.

Agas initially at p1 = 1 bar and occupying a volume of 0.5 liter is compressed within a piston–cylinder assembly to a final pressure p2 = 4 bar. (a) if the relationship between pressure and volume during the compression is pv = constant, determine the volume, in liters, at a pressure of 3 bar. (b) repeat for a linear pressure–volume relationship between the same end states. reference
