To maintain a constant temperature, the Earth must radiate as much light energy every second as it absorbs from the Sun. The Earth receives about 1.74 x 1017 W from the Sun, and absorbs about 70% of the incoming light, reflecting 30% of it back into space. That 70% is the light energy that must be re-radiated by the Earth. The Earth's total surface area is about 5.10 x 1014 m2. If the Earth radiates as a uniform, perfect blackbody, what must its temperature be in order to radiate as much light energy every second as it receives from the Sun

tube or goog will be great resources to find the answer to the question that you're asking

the journeys of marquette, joliet and la salle a) new france expand.

all three of these explorers explored the midwest and the area around the great lakes, which they subsequently claimed for france.

this was a big portion of territory and expanded new france which before then only consisted of quebec province in northeastern canada

part 1: describe the mass and the surface temperature of dwarf stars.

part 2: explain using complete sentences where on the hr diagram you would expect to find a dwarf star based on its physical properties.

part 1: the mass of a dwarf star is very small and the surface temperature of dwarf stars are high and they have the lowest absolute brightness.

part 2: on the hr diagram you would expect to find a dwarf star based on its physical properties at an absolute brightness of -2 to -4

hope this
