Earth is about 150 million kilometers from the Sun, and the apparent brightness of the Sun in our sky is about 1300 watts/m2. Use these two facts and the inverse square law for light to answer the questions.
a) Determine the apparent brightness that we would measure for the Sun if we were located half Earth's distance from the Sun.
b) Determine the apparent brightness that we would measure for the Sun if we were located twice Earth's distance from the Sun.
c) Determine the apparent brightness that we would measure for the Sun if we were located seven times Earth's distance from the Sun.

a) 5200 watts/m^2

b) 325 watts/m^2

c) 26.5 watts/m^2

LOL look at my background photo, ur welcome!

answer: d. a cme increases the amount of energy in the solar wind

explanation:

coronal mass ejections, also called cmes, are large clouds of plasma and magnetic field that erupt from the sun. only when the cloud is aimed at earth will the cme hit earth and therefore cause impacts. high-speed solar wind streams come from areas on the sun known as coronal holes.

igneous rocks also form where plates converge. the subducting plate melts as it sinks into the crust of the earth, and the melt rises into the overriding plate forming volcanoes. metamorphic rocks are formed mainly in the lithosphere, wherever there is high pressure and high temperature. -woods
