You apply 10 N to a machine and the machine applies 10 N to another object. What is the mechanical advantage ? Rocket Science

The mechanical advantage is 1.

Explanation:

Given;

input force, F₁ = 10 N

output force, F₀ = 10 N

mechanical advantage is called force ratio and it is given as;

M.A = output force / input force

M.A = 10 N / 10 N

M.A = 1

This is an ideal machine scenario.

Therefore, the mechanical advantage is 1.

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.
