Answer:
Light waves slow down as they travel from gas to solid.
Explanation:
The speed of light is often quoted with reference to a vacuum. Light travels fastest in a vacuum and in a gas.
When light travels through other media such as solids or liquids, the speed of light is decreased due to absorption and scattering of photons by molecules as well as remissions.
Hence the speed of light decreases from gas to solid.
To solve the problem it is necessary to apply energy conservation.
By definition we know that kinetic energy is equal to potential energy, therefore
PE = KE

Where,
m = mass
g = gravitaty constat
v = velocity
h = height
Re-arrange to find h,

Replacing with our values


Therefore the correct answer is C.
Answer:
That there should be no distinction between a person of certain social standing than another form a different one. They all should be treated the same.
Explanation:
Unfortunately, this experiment showed the reality of today´s society: that eventhough racism, social distiction, bullying, is seen as wrong, it is still happening.
Social standing is very important in the bussiness world and service facilities. People still treat better some community or type of person because they think they are "better" for having something or its believes, it´s in their culture.
In this example, the priest had better service because society thinks that people church-related are better because of their values, type of life, etc.
However, the type of life some people have won´t have to matter when a service is provided. All arethe same.

Answer:
Electricity works by getting a bunch of conductor elements together and creating a flow of electron-stealing patterns through them. This flow is called a current. Conductors need to be surrounded with insulators so the electrons can only go in one direction.
