06. High-altitude mountain climbers do not eat snow, but always melt To see why, calculate the energy absorbed from your body if you: t tirst with a stove (a) eat 1.0 kg of snow at 1.5" C which your body warms to body ten (b) melt 1.0 kg of snow -15° C using a stove and drink the resulting t 2°C, which your body has to warm to 37°C. 1,0 kg of water at An iron boiler of mass 180...
1. The "surface" of the Sun is not sharp boundaries like the surface of the Earth. Most of the radiation that the Sun emits is in thermal equilibrium with the hot gases that make up the Sun's outer layers. Without too much error, we can treat sunlight as blackbody radiation. The total power radiated by the Sun is 3.87×1026W. Given the radius of the Sun is 6.96×108m, what is the surface temperature of the Sun? Suppose the temperature of the...
Question 1: 25% Find the total gravitational force on the Earth from the Sun and Moon, using the axes shown in the figure. Show your work, write your answer in unit vector notation, and keep 3 significant figures on each component in your answer. Moon 7.35 x 1022 kg 3.85 x 108m Sun 1.50 x 1011m 1.99 x 1030kg 5.97 x 1024 kg Earth
The surface of the Sun has a temperature of 5500 ∘C. Treat the sun as a perfect blackbody with an emissivity of 1.0 and a radius of 7.0*10^8 m. Given; the temperature of space is 3.0K and the power that it takes for the sun to radiate into space is 3.9 * 10^26 W. The solar constant is the number of watts of sunlight power falling on a square meter of the Earth's upper atmosphere. Calculate the solar constant given...
If the sun is about 150 Gm away from the Earth, what is the total power that hits the earth? You may assume that the Earth is a disk that faces the sun with a radius of 6378 km and the area is that of a circle of the same radius. (Answer in PW = 1e15 W with three sig figs)
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

The Sun's surface is a blackbody with a surface temperature of 5800 K. a) at what wavelength does the sun emit most strongly? b) what is the total radiated power per unit surface area? c) what is the total radiated power over the entire surface?
The total power emitted by the sun is 4x1026 W. Calculate the Solar Constant, defined as the power per unit area that reaches the earth outside the atmosphere. The distance from sun to earth is 1.49x1011 m.
