How is the movement of planet 1 in this system influenced by the other two objects in this star system

gravity

Explanation:

if a Venus sized object is orbiting a star and a two neptune sized objects are orbiting closely the will pull and yank on the venus sized object heating it up and the star will pull back on the other panlets heating the insides of the planet (take io as an example)

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.
