b) -200 N
c) 500 N
d) -300 N

1= 26.17

2= 1.17

3=30.86

4=5.86

just took the assigment on edge

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.
