Use the weight of the ball that you calculated in activity B to determine how much work would be required to lift the ball 2 meters above the zero position:

the molecules move in straight line until they collide with each other or with the walls of the container. collisions are perfectly elastic; when two molecules collide, they change their directions and kinetic energies, but the total kinetic energy is conserved.

answer

i think the answer is a) as air pressure in an area increases, the density of the gas particles in that area decreases.

hope it

plants need sunlight, water, and carbon dioxide to make food. plants use the raw materials of water, nutrients they absorb from soil, and carbon dioxide to make sugars the plant can use. energy from the sun and chlorophyll are also needed.
