Asteroids are made up of metals and rocky material , while comets are made up of ice ,dust and rocky material.
Answer: Yes I-P-Cl = 90
Explanation:
This is because the angle formed between I-P-Cl is perpendicular hence the angle is 90°
If the angle is either 0 or 180, that means that there is either negative or positive work, so A and D are not correct.
If the angle is 45, then there is still some work involved.
The only option where there is no work done by a force is B. when the angle is between the force and displacement is 90.
Well the answer to number 1 is definitely B
number 2 is B
number 3 is D
Number 4 is C
Hope this helps:)
