If the mass of an object is doubled, its gravitational force will

ANSWER:

If the mass of an object is doubled, the gravitational force will also double.

EXPLANATION:

This is because the 'gravitational force' acting on a body is "directly proportional" to the "mass of the body". According to Newton’s Law of Gravity, a gravitational force equal to the mass of the body acts on the body and it is this gravitation force that attracts the body.

Therefore, gravitational force being directly proportional increases or decreases as the mass of the object increases or decreases.

4.) metal

"-the movement of carbon from the nonliving environment into living things and back to the environment

-carbon is the essential component of proteins, fats, and carbohydrates (which make up all organisms)

-carbon exists in air, water, and living organisms

-producers convert carbon dioxide in the atmosphere into carbohydrates during photosynthesis

-bacteria in the atmosphere cycles through the system in filtration units

-in cellular respiration, carbon is released back into the atmosphere as carbon dioxide

-some carbon is stored in limestone (forming one of the largest "carbon sinks" on earth)

-largest carbon reservoir on earth= limestone

-carbon stored in the bodies of organisms as fat, oils, or other molecules may be released into the soil or air when the organism dies

-this may form deposits of coal, oil, or natural gas (fossil fuels, which increased the atmospheric carbon dioxide)

-fossil fuels store carbon left over from bodies of organisms that died millions of years ago

-they are located in the surface of earth, deep within the earth and beneath the ocean floor."
