A car start from rest accelerate uniformly at rate of 2 m/sec2. Its velocity after 5 seconds will be:

Read below to understand

Explanation:

acceleration = change in velocity / change in time

(a = v/t)

You have acceleration and time given so you need to rearrange the equation to solve for velocity

V = a * t

V = 2 * 5

Velocity is 10 m/s

- Molecules move from high concentrations to low concentrations.

- Molecules are evenly distributed at the end.

Explanation:

Diffusion is a process that involves the movement of solute or gaseous molecules from the region of higher concentration of the molecules to the region of lower concentration of the same molecule.

The movement of diffusing molecules is random and hence, they are evenly distributed in space at the end of the process.
