Which statement best compares momentum and kinetic energy? if you double the velocity of an object, its kinetic energy doubles. but for the same increase in velocity, the momentum increases four times. if you double the velocity of an object, its momentum doubles. but for the same increase in velocity, the kinetic energy increases four times. if you double the velocity of an object, its momentum and kinetic energy doubles. if you double the velocity of an object, its momentum and kinetic energy increases four times.

If you double the velocity of an object, its momentum doubles. But for the same increase in velocity, the kinetic energy increases four times.

Explanation:

We can prove this statement by looking at the formulas for the momentum and kinetic energy of an object.

Momentum:

Kinetic energy:

where m is the mass of the object and v its velocity.

From the two formulas, we see that the momentum is directly proportional to the velocity, while the kinetic energy is proportional to the square of the velocity. Therefore, if we double the velocity, the momentum increases by a factor 2, while the kinetic energy increases by a factor .

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.
