Part A We can estimate the number of photons in a room using the following reasoning: The intensity of the sun's rays at the earth's surface is roughly 1000 W/m? A typical room is illuminated by indirect light or by light bulbs so that its light intensity is some fraction of that value. Assume that on a bright day the light intensity in the room is about one-third of what it is outside. Estimate the intensity of the light that enters the room. Express your answer with the approptiate units. uả pe ? Iroom = Value Units

The Sun has a power of P = 3.85 x 1026 Watts. The Earth is a distance of (on average) 1.49 x 108 km away from the Sun. A solar sail is a distance R = 1.50 x 107 km away from the Sun. What pressure does the light exert on the sail? You can assume that the sail is not being blocked by the Earth in anyway. You can assume the system is completely reflective Make sure to put your answer in terms of mPa (milliPascal) and include appropriate significant figures.
