A spherical radiator has a radius of 3ft and emissivity of 0.5. If radiates 6000 Btu/hr of heat at 3000R, what is the temperature of a surface affected by its radiation?
The solar power striking Earth every day averages 168watts per square meter. The highest ever recorded electricalpower usage in New York City was 13,200 MW. A recordestablished in July of 2013. Considering that present technologyfor solar energy conversion is about 10% efficient,from how many square meters of land must sunlight becollected in order to provide this peak power? (For comparison,the total area of New York City is 830 km2.)

This ideal person is located in a room with a tempature of 65 dregrees F. and has an emissivity of e=0.95 suppose the room has dimensions 4mx9mx18m a) suppose you and your closest 10 friends come into this room and heat it up. suppose your clothes are in equilibium with your skin and have the same tempature and emissivity. Further suppose that your net power into the room remains constant . How long does it take before the room to get to hot say 95 degrees

You are shocked to learn that the Sun (which has a mass of 1M⊙) and Betelgeuse (with a mass of 11M⊙) have both become black holes overnight. Which black hole would have a larger event horizon and why? What do you experience if you fly your spaceship towards the Betelgeuse black hole? Describe any effects on you or the spaceship What would an observer on the other side of the galaxy see when looking at the black holes against the background of the rest of the stars in the Milky Way?
During periods of high activity, the Sun has more sunspots thanusual. Sunspots are cooler than the rest of the luminous layer of theSun’s atmosphere (the photosphere). Paradoxically, the total poweroutput of the active Sun is not lower than average but is the same orslightly higher than average. Work out the details of the followingcrude model of this phenomenon. Consider a patch of thephotosphere with an area of 5.10 × 1014 m2. Its emissivity is 0.965.a) Find the power it radiates if its temperature is uniformly 5800oK,corresponding to the quiet Sun.b) To represent a sunspot, assume 10.0% of the patch area is at4800oK and the other 90.0% is at 5890oK. Find the poweroutput of the patch.

A small sphere (emissivity =0.503 radius=r1) is located at the center of a spherical abestos shell ( thickness =1.74 cm, outer radius= r2; thermal conductivity of abestos is 0.090 J/ (sm c degrees) The thickness of the shell is small compared to the inner and outer radii of the shell. The temperature of the small sphere is 695 degrees Celsius while the temperature of the inner surface of the shell is 352 degrees Celsius, both temperatures remaining constant. Assuming that r2/r1 =8.75 and ignoring any air inside the shell, find the temperature in degrees Celsius of the outer surface of the shell.
A greenhouse 20m long and 15m wide has a nearly flat roof 3m above the floor level. When the sun is directly overhead the solar flux is 1,000 W/m^2. If the glass roof has an emissivity of 0.9 and the convective losses are 0.8 times the radiation losses, what is the temperature in the greenhouse?
The 300-meter radiotelescope in Arecibo, Puerto Rico(Fig. 25–33), is the world’s largest radiotelescope, butmany other radiotelescopes are also very large. Why areradiotelescopes so big? Why not make optical telescopesthat are equally large? (The largest optical telescopes havediameters of about 10 meters.)
