An earth-orbiting satellite has solar energy–collecting panels with a total area of 4.0 m2 . If the sun’s radiation is perpendicular to the panels and is completely absorbed, find the average solar power absorbed and the average radiation-pressure force
The average intensity of sunlight on Earth’s surface is about 700 W/m2 .
(a) Calculate the amount of energy that falls on a solar collector having an area of 0.500 m2 in 4.00 h .
(b) What intensity would such sunlight have if concentrated by a magnifying glass onto an area 200 times smaller than its own?
Solar radiation reaches Earth at a rate of about 1,400 W/m2. If all this energy were absorbed, what would be the average force exerted by radiation pressure on a square meter oriented at right angles to the sunlight?
