2. A bar of silicon is 4 cm long with a circular cross section. If the resistance of the bar (R) is 240 N at room temperature, what is the cross-sectional radius (r) of the bar? (Given the resistivity of silicon is: p = 6.4 × 10² Q.m). 2. A 12-V battery requires a total charge of 40 ampere per hour during recharging. How many joules (energy) are supplied to the battery?
