If weight is the force of gravity on an object, then your weight can change if the force of gravity is different on a different planet?

Yes, (but you may write this incorrectly) weight is defined as the mass of an object times the gravitational acceleration.

as: W = M*g

where, for example, in Earth g = 9.8m/s^2

This means that if you go to a place with a smaller gravitational acceleration (for example the moon) your weight will be smaller (because the gravitational acceleration in the moon is smaller than in the Earth)

i need the answer to this too but idk it ; -;

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.
