Your body is much larger now than it was when you were a baby. What is the cause of this growth? * 1 point
a. All of your cells have grown bigger since you were a little baby, which means you are now bigger.
b. Your body is made up of different types of cells now than it was when you were a baby, and these cells are bigger than baby cells.

c. Your cells have been making copies of themselves, and you are now made up of many more cells than you used to be.

d. When you were a baby all of your cells were prokaryotic, but now that you are older they have all grown into eukaryotic cells.

c

Explanation:

the formula mass of a molecule or a compound is the sum of the atomic weights of the atoms in its empirical formula

(that's what i know about formula mass)

(newtons first law)

conservation of momentum law states :

momentum before collision = momentum after collision

momentum p (kg-m/s)= mass * velocity

say moving car=1 000 kg, velocity = 10 m/s then p = 1 000*10= 10 000 kg-m/s

say still car = 2 000 kg, velocity = 0 m/s then p = 2 000* 0 = 0 kg-m/s

total momentum prior to collision = 10 000 + 0 = 10 000 kg-m/s

momentum after collision = 10 000 kg-m/s

mass now = 1 000 kg+2 000 kg = 3 000 kg

10 000 = 3 000 kg* velocity m/s

10 000/3 000 = velocity

3.33 m/s = velocity after collision

an impulse is a force applied over time , momentum is exclusive of external forces and a perfect collision is implied
