Answer:

Water, carbon dioxide, and oxygen are among the few simple molecules that can cross the cell membrane by diffusion (or a type of diffusion known as osmosis ). Diffusion is one principle method of movement of substances within cells, as well as the method for essential small molecules to cross the cell membrane.

A bus changes its velocity from 5 m/s to 15 m/s in 5 seconds. What is its acceleration?
sladkih [1.3K]

Answer:

\boxed {\boxed {\sf A. \ 2 \ m/s^2}}

Explanation:

Acceleration is the rate of velocity's change with time.

We can calculate it by dividing the change in velocity over time.

a=\frac{v_f-v_i}{t}

Let's define the variables. The final velocity is 15 meters per second. The initial velocity is 5 meters per second. The time is 5 seconds.

v_f= 15 \ m/s \\v_i= 5 \ m/s \\t= 5 \ s

Substitute the values into the formula.

a=\frac{15 \ m/s- 5 \ m/s}{5 \ s }

Solve the numerator first.

  • 15 m/s - 5 m/s= 10 m/s

a=\frac{10 \ m/s}{5 \ s}

Divide.

a= 2 \ m/s/s = 2 \ m/s^2

The acceleration of the bus is <u>2 meters per second squared.</u>
