how many electrons would be in an atom of carbon that has six protons and six neutrons? complete the atom by writing the correct number of electrons in the configuration.

explanation:

an enlarged virtual image is the answer

0.19 m/s and 0.45 m/s

0.11 m/s and 0.28 m/s should be correct

can be answered using momentum.

momentum = p

p1= mass1 * velocity1

p1 = p2

therefore

p1 = 6kg * 4m/s

p1 = 24kgm/s

p2=m2 * v2

24 kgm/s = 7kg * v2

v2 = 24 kgm/s / 7kg

v2= 3.42 m/s
