Is it possible for two different objects to have the same speed but different velocities? Explain your answer.

Yes

Explanation:

Objects have the same velocity only if they are moving the same speed and in the same direction. objects moving at different speeds, in different directions or both have different velocities

yes

Explanation:

speed and velocity are the same thing, except that velocity includes a direction.

ex.

if two things are traveling at 3mi/h, then thats the same speed. but if one is going north and the other south, then those are two different velocities

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.
