A person in a lab wants to make a car accelerate faster. Should the person: O decrease the mass
o increase the mass
O lower the force

Decrease the mass.

Explanation:

By Newton's Second Law we know that net force exerted on a given system equals the rate of change of linear momentum () in time.

(Eq. 1)

When mass of the system has a constant mass, this net force () is reduced to its mass () multiplied by acceleration ():

(Eq. 2)

If we keep net force exerted on system constant, then a decrease on mass is compensated by an increase in acceleration. Hence, correct answer is: Decrease the mass.

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.
