CAN SOMEONE PLEASE HELP ME WITH THIS SCIENCE QUESTION THANK YOU:)

Carbon

Explanation:

Human activities are known to substantially alter the carbon cycle. New strategies applied to land-use systems, burning fossil fuels, and the use of limestone as building material are activities that emit high amounts of carbon into the atmosphere. It is well known that the excess of carbon as carbon dioxide (CO2) into the atmosphere warms the planet because this gas is an important heat-trapping (greenhouse) gas. Moreover, it is also important to note that deforestation also affects the carbon cycle since plants use CO2 during photosynthesis.

explanation:

the universal gravitation equation. since the gravitational force is directly proportional to the mass of both interacting objects, more massive objects will attract each other with a greater gravitational force. if the mass of one of the objects is doubled, then the force of gravity between them is doubled.
