Can someone pls help me

Ok so I hope you read the instructions. You have a simulator and from there you have to find the mass and acceleration. It would be helpful of you could send me the pic of a simulator and I may lead you to the right way.

It already given you the force which is 4 N. Plug it in simulator and then you can send me the picture of it so I can help you further.

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.
