The time average power density of radiation from the sun at the surface of the Earth is about 1550 W/m^2.
a) How much total power is incident on the state of Colorado on a sunny day. Compare this to the average electrical energy consumption of the United States which is on the order of 10^12 Watts.
b) Find the peak electric and magnetic fields of solar radiation.
c)If the radius of the Earth is 6.37Mm (1Mm = 10^6m), the radius of the sun is 700Mm, and the radius of the Earth's orbit around the sun is 1.5x10^8 km, find how much total power the sun emits in Watts.
d) Calculate the force felt by a car with surface area of 1.5 m^2 (Hint: this is a radiation pressure problem, Pressure = ((power flux density)/C)
