The release of pollutants into marine waters can cause harmful algae to bloom. The algae may cover large sections of coral reefs. How do the algae affect the coral? A They harm the coral by preventing them from receiving enough sunlight. В. They benefit the coral by increasing the water temperature. C. They harm the coral by preventing the coral from becoming parasites of the algae. D. They benefit the coral by providing the coral with many nutrients.​

frequency, z, and the collision density, z, in carbon dioxide (co2), r 180 pm at 30 °c and 120 kpa

elements make up everything, and they combine to make compounds.

the answer is c

(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
