A horse runs around a circular track that is 350.0 m long. He runs clockwise from the start line back to the start line, then turns back and goes counterclockwise back
to the start line again. What is the horses displacement?

A. 0 m
B. 300.0 m counterclockwise
C. 300.0 m counterclockwise
D. 600.0 m

A 0m

Explanation:

The horse runs clockwise round the strack, then goes back to the start line ending up back at the same place when it started.

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
