The question is about Distance and Displacement. Distance, a scalar quantity, represents the total path length traveled between two positions, whereas displacement, a vector quantity, refers to the change in position from the starting to the final point, including direction.
When comparing distance and displacement in the field of science, specifically physics, there are key differences to keep in mind. Distance is a scalar quantity that refers to the total length of the path traveled between two positions. In contrast, displacement is a vector quantity—and thus includes both magnitude and direction—that represents the change in position of an object from its starting point to its end point.
Let's consider an example where you drive from home to school which is 5 km away, then return back home. In this case, the distance you traveled is 10 km because distance simply adds up all the lengths covered. However, the displacement is 0 km because displacement considers the direct path from the starting position to the final position; since you returned home, your initial and final positions are identical, and so the change in position is null.
Therefore, it's important to note that while distance and displacement can sometimes share the same magnitude, they are distinct in that displacement always includes direction. Distance is just a measure of how far an object has travelled, while displacement tells you how far and in which direction it is from the starting point.

Answer:
Distance is a scalar quantity that refers to "how much ground an object has covered" during its motion. Displacement is a vector quantity that refers to "how far out of place an object is"; it is the object's overall change in position.
There you go again. Newton's 3rd Law says "for every action there is an EQUAL OPPOSITE reaction.".

If THIS MUCH force pushes the bullet THAT way, then THE SAME amount of force pushes the rifle THIS way.
The bullet pushes backward on the rifle with the same amount of force as the rifle exerts on the bullet.

B) comet
C) earth
D) mars
Comets on average take the longest to orbit the sun (longest period), therefore the correct answer is option B.
It is a system that collection of all the planets and spatial bodies revolving around the sun because of the gravitational pull of the sun.
Our Solar System is based on a heliocentric model in which the Sun is assumed to reside at the central point of the planetary system.
The earth (on average) takes one year to orbit around the sun.
Mars on average takes 1.73 years to orbit around the sun.
astroid on average takes 4-5 years to orbit around the sun.
Comets on average take the longest to orbit the sun (longest period)
Thus, the correct answer is option C.
