The sun delivers roughly 1kwm2 of power to the earth’s surface. a parabolic mirror with a 1.5 m radius is used to focus this energy onto a beaker containing 2 l of water. estimate the time taken by the mirror to rise the temperature of water by 60°c, assuming cp, m= 75291 j k mol and ignoring energy losses to the surroundings.
