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...
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)
Warm Up The surface of the Earth receives approximately 1000 W/m2 (Watts per square meter) of energy from the Sun. This number rises to about 1386 W/m2 in the upper atmosphere (r 6.4 x 106 m) The sun is 1 AU (1.496 x 1011 m) away Over what area is the Sun's energy spread at the Earth's distance? How much power is the Sun releasing?
Warm Up The surface of the Earth receives approximately 1000 W/m2 (Watts per square meter)...
Calculate the average power that the surface of Earth facing the Sun receives from the Sun. Assuming that the Earth is a blackbody and radiates the same amount of power that it absorbs from the Sun, calculate the average surface temperature of the Earth. Does your answer make sense compared to your experience? The Sun’s surface temperature is 5800 K, its radius is 6.96x108 m, the distance between Earth and the Sun is 1.5x1011 m, and the radius of the...
The amount of radiant power produced by the sun is approximately 3.9 × 1026 W. Assuming the sun to be a perfect blackbody sphere with a radius of 6.96 × 108 m, find its surface temperature (in kelvins).
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.
Electromagnetic Wave Questions
2. Our sun has a power output of roughly 3.87 1026 watts (W). This energy is transmitted essentially uniformly in all directions. By the time this radiation reaches the Earth, which has an average distance from the sun of 1.50 x 10" m, what is the intensity? (Recall that intensity is defined to be power per unit area). 3. The energy from the sun is primarily in the infrared and visual wavelengths. The following table gives the...
