How do u get mass when u have 24 newtons of force at 4m/s2

Use the formula from Newton's 2nd law of motion:

Force = (mass) · (acceleration)

Fill in the numbers that you know:

24 N = (mass) · (4 m /s²)

Divide each side by (4 m/s²) :

Mass = (24N) / (4 m/s²)

Mass = 6 kg

cell differentiation  is how generic embryonic  cells  become specialized  cells. this occurs  through a process called gene expression. gene expression is the specific combination of genes that are turned on or off (expressed or repressed), and this is what dictates how a  cell  functions.

explanation:

increase masses, decrease separation
