1.	2. The Sun delivers roughly 1 kW m- of power to theEarth's surface. A parabolic mirror with a l m radius is usedto focus this energy onto a beaker containing 1 L of water.Estimate the time taken by the mirror to raise the temperature of thewater by 50°C, assuming the specific heat capacity of waterto be 4200 JK-l kg and ignoring energylosses to the surroundings.
