A15.0-m length of hose is wound around a reel, which is initially at rest. the moment of inertia of the reel is , and its radius is 0.160 m. when the reel is turning, friction at the axle exerts a torque of magnitude on the reel. if the hose is pulled so that the tension in it remains a constant 25.0 n, how long does it take to completely unwind the hose from the reel?

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.

multiply 2kg by latent heat of vap

god i hope this !
