Question
Information Given: Location:MarsThe Sun hits the Earth with a good 1400 W/square meter.
Distance from Earth to te Sun: 92,960,000 miles (149,600,000 km) Distance from Mars to the Sun: 141,600,000 miles (227,900,000 km)
Questions: a) What is the power per square meter that the Sun provides on Mars? Information Given: Location:Mars
The Sun hits the Earth with a good 1400 W/square meter.
Distance from Earth to te Sun: 92,960,000 miles (149,600,000 km) Distance from Mars to the Sun: 141,600,000 miles (227,900,000 km)
Questions: a) What is the power per square meter that the Sun provides on Mars?
Explanation / Answer
Intensity = power /area i.e I is inversly proportional to r^2
I mars/iearth = (Rearth/Rmars)^2
Imars = 1.496^2*10^22* 1400/(2.279^2*10^22)
Imars = 603.25W/m^2
