What causes items like salt and pepper to be attracted to the balloon?

First, the pepper polarizes much easier than the salt. That is, its electrons move mostly to one side of the pepper flake leaving one end positive and the other negatively charge. The positive end is attracted to the negative balloon. Salt does not polarize quite as much so it doesn’t feel as much of a pull. However it will jump up on the balloon if you hold it very close to the plate.

Second, the pepper flakes are much lighter than the salt crystals. So even if the salt does jump up on to the balloon, it is too heavy to stay and falls back down.

Answer from: leeorareeves299

Explanation: Both salt and pepper grains are attracted to the balloon, and the closer the balloon gets to the grain, the more strongly they are attracted to each other. The force of gravity also play a part in determining which grains stick to the balloon and which stay on the plate.

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.

Assume that a person skiing high in the mountains at an altitude of h = 15100 ft takes in the same volume of air with each breath as she does while walking at sea level. determine the ratio of the mass of oxygen inhaled for each breath at this high altitude compared to that at sea level. assume that the air composition (i.e. % of air that is oxygen) is the same at sea level as it is at 15100 ft.
