A dry cell of emf 1.6 V and internal resistance 0.10 Ω is connected to a resistor of resistance R Ω. If the current drawn from the cell is 2 A (i) What is the voltage drop across R? (ii) What is the energy dissipation in the resistor?
a gas is compressed from a volume of 2m3 to a volume of 1m3 at a constant pressure of 100N/m2. Then it is heated at constant volume by supplying 150J of energy. As a result, the internal energy of the gas increases/decreases by??
