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.

Water is not used as thermometric liquid.why?​
Dima020 [189]

Answer:

Water cannot be used in thermometer because of its higher freezing point and lower boiling point than other liquids .  If water is used in a thermometer , it will start phase change at 0degree\\C and 100degreeC and will not measure temperature , out of this range . This range is very small as compared  to other liquids as mercury , having freezing point about −39degreeC and boiling point 356degreeC.

There is a person who throws a coin vertically downward with an initial speed of 11.8 m/s from the roof of a building, 34.0 m ab
omeli [17]

Answer:

Time taken by the coin to reach the ground is 1.69 s

Given:

Initial speed, v = 11.8 m/s

Height of the building, h = 34.0 m

Solution:

Now, from the third eqn of motion:

v'^{2} = v^{2} + 2gh

v'^{2} = 11.8^{2} + 2\times 9.8\times 34.0 = 805.64

v' = \sqrt{805.64} = 28.38 m/s

Now, time taken by the coin to reach the ground is given by eqn (1):

v' = v + gt

t = \frac{v' - v}{g} = \frac{28.38 - 11.8}{9.8} = 1.69 s

A body accelerates uniformly from rest at 2m/s square. calculate it's velocity after traveling 9m.​
Talja [164]

Answer:

6m/s

Explanation:

Given parameters:

Initial velocity  = 0m/s

Acceleration  = 2m/s²

Distance  = 9m

Unknown:

Final velocity = ?

Solution:

To solve this problem, we use the expression below:

         v²  = u²  + 2as

v is the final velocity

u is the initial velocity

a is the acceleration

s is the distance

        v²   = 0² + (2 x 2 x 9) = 36

        v  = 6m/s
