Currently, fossil fuels are one of the world’s primary energy sources. The graph shows the amount of carbon that has been released in the atmosphere since 1900 due to the burning of fossil fuels. A. The burning of fossil fuels has increased the total energy in the world because the process of combustion releases energy.
B. The burning of fossil fuels has decreased the total energy in the world because it has depleted our fossil fuel supplies.
C. The burning of fossil fuels had decreased the total energy in the world because energy is lost during the process of combustion.
D. The burning of fossil fuels has not changed the total energy in the world because it converts potential energy to thermal energy.

What is the length x of the side of the triangle below? (hint: use the cosine function)

The coulomb's law explains which of the following? select all the force between two charged objects is inversely proportional to the charge on each object. the force between two charged objects is directly proportional to the charge on each object. the force between two charged objects is directly proportional to the distance separating them. the force between two charged objects is inversely proportional to the square of the distance separat coulomb's law is similar to newton's 2nd law. if the force between two objects is f and the charge on both objects is doubled, the new force between the would now be 2f. if the force between two objects is 2f and the distance separating them is doubled, the new force between the objects would now o the be zf.

A3030 cmcm wrench is used to loosen a bolt with a force applied 0.30.3 mm from the bolt. it takes 6060 nn to loosen the bolt when the force is applied perpendicular to the wrench. how much force would it take if the force was applied at a 3030 degree angle from perpendicular? a 3030 cmcm wrench is used to loosen a bolt with a force applied 0.30.3 mm from the bolt. it takes 6060 nn to loosen the bolt when the force is applied perpendicular to the wrench. how much force would it take if the force was applied at a 3030 degree angle from perpendicular?
