True or False. The arrow labeled A represents a transfer of solar energy to chemical energy. Explain why this is true or false.

Which arrow or arrows represent a release of carbon dioxide? What process is occurring at the arrow(s) you selected?

Which arrow or arrows indicate a process that cycles carbon from living or nonliving organisms? Describe the process or processes you selected.

Which arrow or arrows represent reactions that demonstrate a conservation of mass and energy? Explain your answer.

answer: i dont know the answer but this might

explanation:

l

(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
