Answer: Correct option is C) because momentum is conserved

 

Explanation:

According to law of conservation of linear momentum if net external force on a system is zero then the total momentum of the system will be conserved .

<u>For a collision occurring between object 1 and object 2 in an isolated system</u>

If we consider the two colliding object as a single system then while collision the total momentum of the two objects before the collision is equal to the total momentum of the two objects after the collision.

Thus momentum before collision equal the momentum after a collision because momentum is conserved .

Calculate the average orbital speed of Ceres in
marin [14]
] Ceres is composed of rock and ice and is estimated to comprise approximately one third of the mass of the entire asteroid belt. Ceres is the only object in the asteroid belt known to be rounded by its own gravity (though detailed analysis was required to exclude 4 Vesta). From Earth, the apparent magnitude of Ceres ranges from 6.7 to 9.3, peaking once every 15 to 16 months,[21]hence even at its brightest it is too dim to be seen with the naked eye except under extremely dark skies.

What is the role of equations in this course?
Karolina [17]
That will depend on which course you're talking about. It will be a minor role in, say, Maritime Law or Comparitive Religion, but a major one in, say, Particle Physics or Linear Algebra.
