Answer:

Magnitude = 26 m

Direction = eastward

Explanation:

Given that a football coach walks 24 meters eastward, then 12 meters westward, then 36 meters eastward, and finally 22 meters westward. What is the magnitude and direction of the displacement?

Let eastward be positive and westward be negative.

Magnitude = 24 - 12 + 36 - 22

Magnitude = 60 - 34

Magnitude = 26

Since the answer is positive, the direction will be eastward.

Therefore,

Magnitude = 26 m

Direction = eastward

**Answer:**

Fundamental unit is any unit that is not dependent on other units and other units can be derived from them

**Explanation:**

Units such as Kilogram, Mass and Time are said to be fundamental units because they are independent.

Differences between Mass and weight;

1. Mass is the measure of the amount of matter in a body while weight is a measure of how the force of gravity acts upon that mass.

2. Mass is a scalar quantity while weight is a vector quantity

1. It produces heat in various parts which means some useful energy is lost as heat.

**Answer:**

**The car exerts a force on the truck which is c.) 6000 N.**

**Explanation:**

If the truck exerts a force of 6000 N on the car then according to Newton's Third Law of Motion that every action has an equal and opposite reaction we can say that **the force exerted by the car on the truck is 6000 N.**

The only reason the truck is able to move the car is because of the frictional forces. That is frictional force of the trucks tires on the surface of the road and the frictional forces of the cars tire on the surface of the road, and since these forces are not equal this therefore gives rise to motion.

**Answer:**

an instrument for measuring an electromotive force by balancing it against the potential difference produced by passing a known current through a known variable resistance.
