A planes velocity changes from 0 m/s to 60 m/s in 20 seconds. What is its
acceleration?
3 m/s2

3 m/s

0.3 m/s2

0.3 m/s

Option A. 3 m/s2

Explanation:

Given data: Initial velocity = 0 m/s

Final velocity = 60 m/s

Time taken = 20 seconds

Required : acceleration = ?

Solution: We know that

Acceleration = final velocity - initial velocity / time taken

Acceleration = 60 m/s - 0m/s ÷ 20 s

Acceleration = 60 m/s ÷ 20 s

Acceleration = 3 m/s2

So the acceleration produce in the body is 3 meter / second square.

humans can cause extinction of a species through overharvesting, pollution, habitat destruction, introduction of invasive species (such as new predators and food competitors), overhunting, and other influences. explosive, unsustainable human population growth is an essential cause of the extinction crisis.

when the displaced particles are perpendicular to the direction the wave travels, is called a transverse wave, whereas in longitudinal wave the displace practices are parallel to the direction of the wave.

in the given image:

first image shows - longitudinal wave

second image shows - transverse wave

third image shows - longitudinal wave

fourth image shows - longitudinal wave
