Extra Credit: In our solar system, large dust particles, similar in size to soot and sand grains, are common but smaller particles are largely absent. It is believed that these smaller particles have been blown out of the solar system by the radiation force exerted on them by the Sun. Assume that the dust particles are spherical, completely absorb all incident radiation from the Sun, and have a density of 2,000 kg/m3. Determine the diameter, in nanometers, of the smallest...

4. A space boat is to be designed such that the solar radiation power on its sail counters the sun's gravitational force. Assume that total weight of the boat is 1000 kg Calculate the surface area of the sail Note: The mean distance between earth and sun is 1.5x1011m, the mass of the sun is 1.99x1030kg, the gravitational constant is 6.67x10-11m/s2, the total solar radiation power density on earth is 1.4 kW/m2

1. a)The mass of Mercury is 3.3 × 10^23??. About 30% of its total mass is silicate material. Assume that we are able to convert 0.1% of the mass of the silicate material on Mercury to crystalline silicon, how many solar panels can we build? Also assume that our solar panels are square-shaped sheets completely made out of crystalline silicon. Use the following numbers for your estimation: density of silicon is 2300??/?^3 ; thickness of the solar panels is 0.5??;...
