Will give brainliest! twenty points ! 1. why is a spectrometer important to astronomers? a.) spectrometers measure distances to stars. b.) spectrometers give us data on the light we cannot see with our human eyes. [i think this one might be the answer, but i'm unsure] c.) spectrometers launch telescopes into space. d.) spectrometers are in needed to look at distant stars from earth. 2. which measurement system would we use to measure within the solar system? a.) astronomical unit b.) light year c.) parsec [i think this is the right answer]

Silver tarnishes as silver metal reacts with hydrogen sulfide, h2s, in the air. in this reaction, dark silver sulfide, au2s, covers the surface of silver. when silver is polished, this coating of silver sulfide can be removed from the surface. this makes the silver shiny again. enter the coefficients that balance the tarnishing reaction equation. (type 1 for no coefficient.)

Rocks, as they are compressed, begin forming mountains above the earth's surface when two continental plates converge. the continental crust increases in depth as the mountains grow above. the himalayan mountains formed at a convergent plate boundary in this manner. the rocks are smashed together causing them to due to the intense heat and pressure from the colliding plates and eventually forming rock. a) melt; igneous b) layer; sedimentary c) recrystallize; metamorphic d) melt into the earth's interior; metamorphic

Why does earth rotate? because earth is formed from cold gases collapsing due to gravity because the matter in the nebula that formed earth was spinning because earth forms more than 99% of the mass of the solar system because the hydrogen atoms inside the nebula fused to form helium
