How does Astronomy differ from the other physical sciences?

i don't understand is there any other way you can rephrase it plz let me know in the comments and i will do it.

explanation:

c) up is the direction the magnetic force is acting on the charge.

it is a negative acceleration

blue light is scattered in different directions by the tiny molecules of air. blue is scattered more than other colours because it has a shorter distance to travel which results in smaller waves. this is why we see a blue sky most of the time.
