The Sun delivers roughly 1 kW m −2 of power to the Earth's surface. A parabolic mirror with a 1 m radius is used to focus this energy onto a beaker containing 1 L of water. Estimate the time taken by the mirror to raise the temperature of the water by 50 ∘ C, assuming the specific heat capacity of water to be 4200 J K −1 kg −1 and ignoring energy losses to the surroundings.
