Explain how to create a Bohr model for the element carbon

In order to create a Bohr model for carbon, you must start in the first shell of electrons. The first shell can hold up to 2 of carbons 6 electrons. After filling up the first shell you can move on to the second that can hold up to 8 electrons. The finished Bohr model would have 2 electrons in the first shell and 4 in the second shell.

Explanation:

i believe the answer is a.

(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
