Which has more acceleration when moving in a straight line- a car increasing its speed from 50 to 60 km/h or a bicycle that goes from zero to 10 km/h in the same time?

We use the formula,

Here, a is acceleration, u is the initial velocity, v is final velocity.

Let t hour be the time for both car and bicycle increasing its speed.

The acceleration of the car,

The acceleration of bicycle,

Thus, the accelerations for both car and bicycle for their increasing speed in same time will be same.

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.
