I’m a really nice person I am kind I love sharing I’m smart but I still get bullied at school because I’m not like every one else and also because my last name is Dixon I have been dealing with this for the past 13 years and now I am tired of it what should I do

Dude, just stand out for yourself. Dont just hold that inside of u. Go workout become stronger. And show them who u really are. Dont just stand there, be the best. And my advice as a Junoir, just be yourself.

Explanation:

Tell an adult, and if you have a counselor ask them

Explanation:

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.
