When Marshall takes his pet dog for a walk, the dog walks at a very consistent pace of 0.55 m/s. Draw a motion diagram and position time graph to represent Marshall's dog walking the 19.8-m distance from in of his house to the nearest stop sign.

Explanation:

Given that,

Speed of the dog is 0.55 m/s and it is constant.

We need to draw position-time graph to represent Marshall's dog walking the 19.8-m distance from in of his house to the nearest stop sign.

We can find time using definition of speed.

The attached figure shows the position-time graph of Marshall's dog.

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
