An aeroplane is circling in the sky at a speed of 150 m s-1. The aeroplane describes a circle of radius 20 km.
For a passenger of mass 80 kg inside this aeroplane, calculate:
(a) Passenger's angular velocity
(b) Passenger's centripetal acceleration
(c) the centripetal force acting on Passenger *

this means that the temperature of both substances will be equal

305.7

explanation:

density =m/v

density =917/3.00

density = 305.

approximately = 305.7

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.
