You could increase the mechanical efficiency of this screw by

adding more threads to the screw

reducing friction along the screw threads

making the screw threads longer

making the inclined plane longer

You could increase the mechanical efficiency of this screw by reducing friction along the screw threads

the answer is the second option now u can give her brainliest.

are there options? cause you ain’t. real specific

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.
