PLEASEEE HELPPP I WILL GIVE BRAINLIEST What if you drop a heavy, metal anvil and a flat piece of paper from a bridge at the same time. Which one will hit the water first: If they are in a vacuum (in the absence of air resistance)? ___. If they are under normal atmospheric conditions (normal air)? ___.

it takes about 30 days for it to break down

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.
