Meteors and Comets Have you ever seen a shooting star? These sudden bright
streaks are called meteors. A meteor is a streak of light produced when a small
piece of rock or ice, known as a meteoroid, burns up as it enters Earth's
atmosphere. You can see a meteor on almost any clear night.
Comets are rarer sights than meteors. A comet is a cold mixture of dust and ice
that develops a long trail of light as it approaches the sun. When a comet is far
from the sun, it is frozen. As it gets close to the sun, the cloud trailing behind the
comet forms a glowing tail made up of hot dust and gases.
Perhaps the most famous comet is Halley's Comet. This highly visible comet was
documented by Edmund Halley, who calculated its orbit and predicted its next
appearance in the sky. Sure enough, the comet appeared as he predicted in
1758, although Halley didn't live to see it. It has continued to appear about every
75 years, last appearing in 1986.

So the question is how close was Halley’s Comet to Earth in 1910? create an equation to answer the question

This seems like a lot but it isn’t I REALLY NEED HELP!!

Stay safe everyone

Each of the following reactions is allowed to come to equilibrium and then the volume is changed as indicated. predict the effect (shift right, shift left, or no effect) of the indicated volume change. drag the appropriate items to their respective bins.co(g) + h2o(g) < => co2(g) + h2(g) (volume is decreased) pcl3(g) + cl2(g) < => pcl5(g) (volume is increased) caco3(s)< => cao(s) + co2(g) (volume is increased)
