В закрытой с одного конца U-образной трубке содержатся три столбика одинаковой жидкости (тёмные участки) и пузыри воздуха
(белые участки). Вертикальные участки трубки соединены тонкими
горизонтальными трубочками с закрытыми кранами (К 1 и К 2 ). В каком
направлении начнут двигаться столбики 2 и 3 жидкости, если открыть
кран К 1 ? (↑ – вверх, ↓ – вниз).

whichever one it is, it's definitely not one that you included on the list you provided.

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.

the displacement produced by the body.  

the amount of force subjected to the body.  

the angle between the direction of force and displacement
