What happens when the threat of exposure to dirty air is reduced in a community?
there is enough oxygen available for people's lungs to function normally
the amount of indoor air pollutants released during a fossil fuel burn decreases
there is a minimal exposure risk to the outdoor dirty air pollutants like carbon monoxide and radon.
the risk of experiencing digestive related diseases from exposure to a buildup of dirty air is low

The diagram below shows the movement of particles. what does this piece of evidence best support? the collision theory the maxwell-boltzmann distribution the effect of pressure on reaction rates the effect of temperature on reaction rates

Imagine that a new planet is discovered with two moons of equal mass: moon a and moon b. the mass of the new planet is greater than the combined mass of its moons. moon a is farther away from the new planet than moon b. what is the planet's gravitational pull on moon a compared to the planet's gravitational pull on moon b? the planet's gravity repels moon a with a greater force than it repels moon b, which is why moon a is farther away. the gravitational pull on moon b is greater than on moon a because moon b is closer to the new planet than moon a. the gravitational pull on moon b is greater than on moon a because moon b is farther away from the new planet than moon a. the gravitational pull on moon a is the same as the gravitational pull on moon b because distance does not affect the planet's gravity.
