Which of the following characterizes erikson's identity versus role formation stage? reconciling relationships with family and friends struggling to develop new skills and obtain new knowledge figuring out how to determine who should be trusted determining one's sense of individuality and place in society

I think that the best one is determining one's sense of individuality and place in society.

Determining one's sense of individuality and place in society

Explanation:

This is the fifth stage of Erickson’s eight stages of psychosocial development which occurs in the age range of 12-18.

In this stage adolescent's try to figure out what kind of person they are i.e., finding one's self. In this stage people try different things to know their likes and dislikes. In order to find their likes and dislikes they try different things to understand their place in the world i.e, they will understand their role that they will occupy.

c. magnitude and direction

speed of light in vacuum is 300,000 km/s

speed of light in other mediums is given by the expression v = c/n, where c is the speed of light in vacuum and n is the refractive index of medium.

for the first medium v = 200,000 km/s

  so, refractive index of medium = 300000/200000 = 1.5

    1.5 refractive index is usually for glass. so first medium is glass.

for the second medium v = 250,00 km/s

so, refractive index of medium = 300000/250000 = 1.2

    1.2 refractive index is usually for water. so second medium is water.

for the third medium v = 0 km/s

so, refractive index of medium = 300000/0 = ∞

    ∞ refractive index is usually for opaque mediums. so third medium is opaque medium.
