Adan skips 25 m South, then runs 100 m North, then walks 25 m Sout
What is her displacement?

I think its 50 north.

Explanation:

25 south then 100 north makes it 75 north then 25 south makes it 50 north.

what is the speed of a softball that travels 20m in 2secs

speed = 20/2 = 10 m/s

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
