How has the United States government tried to preserve water sources?

Implement rainwater harvesting systems to collect and store rainwater for drinking or recharging underground aquifers. Build wells to extract groundwater from underground aquifers. Provide home water-treatment capability through the use of filters, solar disinfection, or flocculants, to make drinking water safe.

Explanation:

the government of the United States preserves water sources by making waste water treatment and preventing water pollution

answer: the rate of diffusion increases with increase in temperature.

increase in temperature, increases the molecular/particles speed (kinetic energy. diffusion means movement of particles through the material.

generally, the heavier the particle the more it interacts with the environment and more the temperature matters. so higher temperature results in higher diffusion.

d: the voltage of the secondary coil is less than that of the primary coil.

im not suree sorry if wrong
