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 :
The molality of a solution is expressed as the amount of the solute in moles per mass of the solvent in kilograms. In this case, the molality is equal to 400 g/62.07 g/mol/ 4 kg water. The molality is equal to 1.61 molal. The freezing point depression is determined through Tf- Kb*molality. Substituting, 0 deg - 1.86 * 1.61 m is equal to -2.99 degrees celsius.

Correct answer is:
,,Atoms can react together, be separated from each other, or be rearranged via chemical reactions. "
