The curved surface area and volume of a cylinder are 44 cm^2 and 38.5 cm^3 Find the radius of the cylinder.

A 500 Omega resistor connected to an external battery is placed inside a thermally insulated cylinder fitted with a frictionless pistion. The cylinder contains an ideal gas. A current i of 200mA flows through the resistor as shown in the figure. The mass of the piston is 10kg. Assuming g = 10m//s^(2) , the speed at which the piston will move upward, due to heat dissipated by the resistor, so that the temperature of the gas remains unchanged is
