Explain the 8 stages of Erikson’s Psychosocial Development.
Artyom0805 [142]

Answer:

Stage 1: Infancy: Trust vs. Mistrust.

Stage 3: Preschool Years: Initiative vs. Guilt.

Stage 4: Early School Years: Industry vs. Inferiority.

Stage 6: Young Adulthood: Intimacy vs. ...

Stage 7: Middle Adulthood: Generativity vs. ...

Stage 8: Late Adulthood: Ego Integrity vs. ...

The key idea in Erikson's theory is that the individual faces a conflict at each stage, which may or may not be successfully resolved within that stage. For example, he called the first stage 'Trust vs Mistrust'. If the quality of care is good in infancy, the child learns to trust the world to meet her needs.

A car initially traveling at 15 m/s North accelerates to 25 m/s North in 4 seconds. The magnitude of the average acceleration is
GarryVolchara [31]

The average acceleration of the car as it accelerates from 15 m/s to 25 m/s will be 2.5 m/s².

<h3>What is Average acceleration?</h3>

Average acceleration is the average rate of change of velocity with respect to time. Mathematically -

a = Δv/Δt

Given that a car is traveling at 15 m/s in north direction and in 4 seconds it accelerates to 25 m/s in the north direction only. Therefore, we can write -

initial velocity [u] = 15 m/s

final velocity [v] = 25 m/s

time taken [Δt] = 4 s

The magnitude of the average acceleration can be calculated as follows-

a = Δv/Δt

Δv = v - u = 25 - 15

Δv = 10 m/s

Therefore -

a = 10/4

a = 2.5 m/s².

Therefore, the average acceleration of the car will be 2.5 m/s².

Lien uses a spring scale to pull a block toward the right across the lab table. The scale reads 8 N. Which force should Lien con
lana66690 [7]

Answer:

<h2>Frictional force</h2>

Explanation:

For the block placed on the table, there are several force acting on the body along the horizontal and vertical axis. All this forces tends to keep the body in a state of equilibrium.The forces acting along the horizontal are the moving force (Fm) and the frictional force (Ff).

Frictional force are forces that acts opposite to the force that causes the body to move (moving force).

If Lien uses a spring scale to pull a block toward the right across the lab table and the scale reads 8 N, this means that the force that causes the body to move is the 8N force (moving force).

Taking the sum of force along the horizontal;

\sum fx = ma_x

Since the body is static, max = 0

\sum fx = 0\\fm+(-Ff)= 0

Note that the frictional force acts is the force of opposition acting in the negative x direction.

fm = 0+Ff\\fm = Ff

Since Fm = 8N, Ff will also be equal to 8N.

Based on the above proof, Lien can also conclude that 8 N is a frictional force
