Io, a satellite of jupiter, has volcanoes that send plumes of matter over 500 km high. the acceleration due to gravity on io is only 1.81 m/s2, and io has no appreciable atmosphere. assuming that there is no variation in gravity over the distance traveled, what must be the speed of the material just as it leaves the volcano in order to reach an altitude of 500 km?

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.

higher potential

explanation:

because it is in a high speed so it must move into a of high potential
