m.
The average amount of solar power reaching the earth is approximately 1 .4 kW/m'. The radius of the x108 m and the distance between the earth and the sun is 1.5x1011 m. The power radiated the sun is 6.25x10' W/m2. Assume the source of energy for the sun is the fusion reaction 4HHe +2(B+2v+ energy Estimate how much hydrogen...

At our distance from the Sun, the intensity of solar radiation is 1370 W/m^2 . As discussed in class and in the textbook, the temperature of the Earth is affected by the greenhouse effect of the atmosphere. This phenomenon describes the effect of absorption of infrared radiation by the surface so as to make the surface temperature of the Earth higher than if it were airless. The average global surface temperature of the Earth is ~288 K. Calculate the surface...

At our distance from the Sun, the intensity of solar radiation is 1370 W/m2. The temperature of the Earth is affected by the greenhouse effect of the atmosphere. This phenomenon describes the ef- fect of absorption of infrared light emitted by the surface so as to make the surface temperature of the Earth higher than if it were airless. For comparison, consider a spherical object of radius r with no atmosphere at the same distance from the Sun as the...

The total power consumption by all humans on earth is approximately 1013 W. Let�s compare this to the power of incoming solar radiation. The intensity of radiation from the sun at the top of the atmosphere is 1380 W/m2. The earth's radius is6.37�106 m. What is the total solar power received by the earth? By what factor does solar power received by the earth exceed the total human power consumption?

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

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...
