n a location where the train tracks run parallel to a road, a high-speed train traveling at 60 m/s passes a car traveling at 30 m/s in the opposite direction. How long does it take for the train to be 180 m away from the car? Group of answer choices

Time taken for the train to travel 180 m away from the train is 2 sec.

Explanation:

velocity of the train = 60 m/s

velocity of the car = 30 m/s

Relative to the other, each vehicle passes the other with a velocity of

V = 60 m/s + 30 m/s = 90 m/s

If we take the car's speed as the reference speed, the speed of the train will be 90 m/s. Therefore, time taken for the train to travel 180 m away from the car is,

time = distance/speed = 180/90

time = 2 sec

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.
