Why should/shouldn't Pluto be reclassified as a planet?​
Scorpion4ik [409]

Answer:

(This could be opinion based, but ok.)

Explanation:

should:Pluto was known as a planet for 75 years. This means that most people already knew it as a planet, and would be extremely confused. All of the books about planets would be inaccurate and changed. Not all people can access brand new books, leading to inaccurate information.

shouldn't: The same reason that it was unclassified as a planet. It does not adhere to all of the rules of being a planet. It is not completely round and does not have a round orbit around the sun. Pluto does not have every requirement to be a real planet, and therefor, it would be incorrect to have it classified wrongly.

We also know that the astronaut’s weight on Earth is 156.6 pounds. Which equation models the situation? no links pls they didn't
Klio2033 [76]

Given what we know, we can confirm that the equation to model the situation can be created by multiplying the mass of the astronaut by the force of gravity on earth.

<h3>What is Mass and the force of gravity?</h3>
  • Mass is the amount of matter in an object or body.
  • What we refer to as weight, is really the force being applied by an object together with the force of gravity.
  • Gravity is an invisible force applied by the earth on all objects.
  • Together will mass, these forces create what we know as weight.

Therefore, we can confirm that the equation to model the situation can be created by multiplying the mass of the astronaut by the force of gravity on earth, which would be 7.2 kg of mass multiplied by 9.807 m/s² which will result in a "weight" of 156.6 pounds or 71 kg.
