If you borrow your mom's car to drive 128 m to the store, but you go cruising instead and drive a total distance of 1256 m in 3600s. What was your speed during the
trip? Round answer to 2 significant figures.

v = 0.349 m/s

Explanation:

If you borrow your mom's car to drive 128 m to the store, but you go cruising  instead and drive a total distance of 1256 m in 3600s.

We need to find your speed during the  trip. It is equal to the total distance divided by time taken.

He has done cruising  instead and drive a total distance of 1256 m.

So,

So, the speed of the person during the trip is 0.349 m/s.

newton's first law of motion

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.
