Question

1. When kinctic energy is conserved in a classical two-body collision, then which of the following best describes the momentum after the collision? A. it will always double B. it might be conserved C. it must always be equal to zero D. it must always be less E. it will also be conserved 2. An example of a vector quantity is which of the following? A. mass B. volume C. velocity D. temperature E. speed 3. Which of the following states of matter is generally associated with the highest temperatures? A. liquid B. metallic solid C. gas D. solid E. plasma

Explanation / Answer

Solution:

1.) Ans: E it will also be conserved.

Momentum is always conserved.

2.) Ans: C Velocity

Velocity has both magnitude and direction.

3.) Ans:E Plasma.

I hope you understood the problem, If yes rate me!! or else comment for a better solution.
