The intensity of solar radiation at the top of the Earth's atmosphere is 1 402 W/m2. Assuming 60% of the incoming solar energy
reaches the Earth's surface and you absorb 50% of the incident energy, find the amount of solar energy you absorb if you
sunbathe for 64 minutes. (Suppose you cover a 1.5 m × 0.3 m section of beach blanket and the elevation angle of the Sun is
60°.)
