omets are made of Chunks of rock, gas, Ice, and dust. The Answer is A and C.</h2>
Explanation:
Comets is one of the main types of space rocks. Recent researchers has termed Comets as 'dirty snowballs' of space, that contains ice, rock, gas and dust. The solid center of the comet is less than 10 kilometers across.
Comets are believed to have originated beyond Neptune and Pluto. It is called the Oort Cloud that surrounds the solar system.
It carries carbon dioxide, methane, ammonia, and many more gases. According to Astronomers, comets are assumed to be the leftovers of the material that was initially the part of solar system about billion years ago.

I experienced these the past few days...
but hoped I helped ^_^
Each point in the chain supports the weight of all the mass below it.
At the bottom end of the chain, the weight is (175 x 9.8) = 1,715 N .
At the top of the chain, the weight is (175 + 12) x (9.8) = 1,833 N .
The tension in the chain varies linearly from 1,715N at the bottom
to 1,833N at the top.

Explanation:
Law 1 states an object at rest , stay at rest and an object in motion stays in motion unless acted on by another force.
Law 2 states that the acceleration of an object depends on its mass and force applied.
Law 3 states every action creates an equal and opposite reaction.
The larger the mass the mass and the speed, the larger the force it would produce if it crashes something. Some car crashes produce minor injuries because maybe this car is small and runs at very slow speed which would mean less force when in impact with another. However, if a big truck crashes, it is expected to produce a larger force causing catastrophic injuries.
