Answer:

Explanation:

The earth turns on its axis every day; it orbits the sun, just like all the other planets in our Solar System. When viewed from space, it turns counter-clockwise.

Because it rotates around the earth at the exact same speed as it rotates around its own axis, so that the same side of the moon is constantly facing the surface of the earth.

Tilt of the earth on its axis is responsible for season formation. The amount of sunlight obtained by various regions on earth surface is regulated by tilt. The places of earth that are facing the Sun and get direct sunlight experiences summers while the others which are facing away from the Sun experience winter season.

The forces acting on the book are normal formal force which act or exerts by the table on the book while on the other hand, gravity is a force that acts in the downward direction. Friction is the force that acts against the motion of the book and is responsible for lowering speed of the book that is sliding on the surface of the table.

Vadim26 [7]

Answer:

Drive-reduction theory

Explanation:

Drive reduction theory is a motivation theory which is based on the principle that organisms are born with certain psychological needs and that they experiment a state of tension when these needs are not satisfied.

This state of tension pushes them to find a way to satisfy those needs, and when those needs are satisfied again, drive is reduced and the person returns to a state of homeostasis and relaxation.

According to this theory, <u>motivation happens when we experiment the state of tension and it's this motivation that drives us to satisfy our needs and be able to feel better. </u>

Dr. Williams is a psychologist who believes that motivation is produced when we feel an uncomfortable internal state that pushes us to find a way to feel better.

In this case, Dr. Williams thinks that our motivation originates from an uncomfortable state (state of tension) that pushes us to find a way to feel better (in order to reduce the drive and be back to homeostasis).

We can observe that Dr. Williams belief is very similar to the drive-reduction theory.

Note:

<u>a) Incentive theories of motivation state that people are motivated by incentives that are given to them (either internally or externally) when they do a expected behavior.</u>

<u />

<u>b) Maslow's hierarchy of needs states that our needs are based on a hierarchy in form of pyramid in which we first need to satisfy the needs at the bottom (physiological needs) to be able to proceed with the other needs that are higher on the hierarchy until we reach the self-fulfillment needs. </u>

<u />

<u>d) Instinct theory states that we are driven by instinct that we need to satisfy in order to experience balance and homeostasis. </u>
