What is the force of friction acting on an object that has an applied force of 10 n and is moving at a constant velocity of 3 m/s to the right?

10N in the opposite direction

Explanation:

If the sum of ll forces are zero: ∑F = ma = 0,

the acceleration a = 0. If the acceleration is zero, the velocity is constant.

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.
