Complete the statements about the law of conservation of momentum.
vitfil [10]

Answer:

The law of conservation of momentum states that the total momentum of interacting objects does not change.

This means the total momentum before a collision or explosion is equal to the total momentum after a collision or explosion.

Explanation:

The law of conservation of momentum is derived from Newton's third law of motion which states that action and reaction are equal and opposite.

The law of conservation of momentum can be stated as follows.

For a collision occurring between object 1 and object 2 in an isolated system, the total momentum of the two objects before the collision is equal to the total momentum of the two objects after the collision.

Describe a human activity that disrupts the carbon cycle and the consequences of that disruption

The Carbon Cycle refers to photosynthesis, during which plants take the CO2 we make and release it back into the atmosphere. One way this process could be interrupted is if a company cuts down a lot of trees for land, destroying many of the plants that keep the Carbon Cycle moving.

Hope this helped, good luck :)
