Cellular respiration and photosynthesis are essentially opposite processes. Photosynthesis is the process by which organisms make high-energy compounds -- the sugar glucose in particular -- through the chemical "reduction" of carbon dioxide (CO2). Cellular respiration, on the other hand, involves the breakdown of glucose and other compounds through chemical "oxidation." Photosynthesis consumes CO2 and produces oxygen. Cellular respiration consumes oxygen and produces CO2.
Carbon dioxide (CO²) is taken in to start the Calvin Cycle.
If we have:
m₁ as the mass of the first satellite
m₂ as the mass of the second satellite
v₁ as the velocity of the first satellite before the connection
v₂ as the velocity of the second satellite before the connection
v₁' as the velocity of the first satellite after the connection
v₂' as the velocity of the second satellite after the connection
The momentum is conserved following this equation:
m₁v₁ + m₂v₂ = m₁v₁' + m₂v₂'
If the collision is perfectly elastic or the two satellites connect perfectly and move with a single velocity:
m₁v₁ + m₂v₂ = (m₁ + m₂)v'
where v' is the velocity of the two connected satellites
