It’s a or b i think it’s b
Its c ok im sorry if i got the last answer wrong
The change in the velocity = 4 m/s
Acceleration = 4 m/s²
<h3>Further explanation</h3>
Given
vo = initial velocity = 4 m/s
vf = final velocity = 8 m/s
t = 1 s
Required
The change in the velocity
Acceleration
Solution
the change in velocity =

Acceleration = ratio of a change in velocity and the time

Input the value :

answer is A
The kinetic theory is used to explain the behaviour of gases.
One of the assumptions states that "a gas is composed of a large number of identical molecules moving at different speeds".
Well people say the world's going to end soon so people need to find another planet to live on they're thinking about Mars at the moment
