The principle of conservation of energystates that energy is neither created nor destroyed. which of thefollowing describes the transformation of energy in thisproblem? a. conservation of energy does not apply toproblems involving nonconservative forces. thus, the potentialenergy slowly disappears during albertine's trip. b. the potential energy was turned intoalbertine's kinetic energy, which was then converted into internal(thermal) energy. c.the potential energy was turned intoalbertine's kinetic energy, which is now stored in the floor asfrictional potential energy. d. the potential energy was turned into elasticfrictional energy, creating the frictional force.

the statement that describes the transformation of energy is statement B (The potential energy was turned into Albertine's kinetic energy, which was then converted into internal(thermal) energy.)

Explanation:

Law of conservation of energy states that energy can neither be created nor destroyed; rather, it can only be transformed or transferred from one form to another.

Throughout Albertine's journey, no energy was lost. Her potential energy was converted to kinetic energy and then to thermal energy of the body.

answer: the exterior temperature of commercial jet planes as they leave the stratosphere and return to the ground increases steadily.

explanation:

the lower most layer of atmosphere is troposphere which extends from 0 to 12 km above the surface of the earth. the temperature initially decreases as distance is increased from the earth's surface. commercial jets fly in lower part of the stratosphere. the stratosphere extends upto 50 km. the temperature in stratosphere starts rising again due to presence of ozone which traps the uv rays.

thus, when the planes leave the stratosphere and return to the ground, the exterior temperature increases steadily.
