To find the power radiated per unit area of the surface, we do not need to make any assumptions about the shape of the star because P / A depends only on temperature.

WebJan 14, 2009 · by Rebecca Lindsey January 14, 2009. The Earth’s climate is a solar powered system. Globally, over the course of the year, the Earth system—land surfaces, oceans, and atmosphere—absorbs an average of about 240 watts of solar power per square meter (one watt is one joule of energy every second). The absorbed sunlight drives photosynthesis ... WebYorozu created her perfect sphere without opening her domain, so the only effect her domain had was making it a sure-hit. Unlike, for example, Hakari's domain which has the unique effect of activating his unlimited CE mode if he hits the jackpot, or Higuruma's which will activate a unique effect depending on Judgeman's verdict. john truschel gordon college

WebSolution: The radiation from the Sun has the same intensity in all directions, so the rate at which it reaches the Earth is the rate at which it passes through a sphere centered at the Sun with a radius equal to the Earth’s orbit radius. The 1350W=m2 is the intensity, or the magnitude of the Poynting vector.

How much power does the sphere radiate

http://indem.gob.mx/Penis/chinese-cures-for-9bb-erectile-dysfunction/ WebSince the diameter is 2 centimeter, the radius will be 1 centimeter, so 4 pi times 0.01 meter square times. The fourth power of the temperature, the temperature we have calculated, is 1449 kelvin to the power 4 point. So the rate of power radiation due to the sphere equals 3.14 times 10 to the 2 rts or we can say the rate of power.
