u a boy or girl ??! i jus wanna know
Answer:
The United States has a good amount of freshwater supply over most of the territory, because the American territory is ripe with lakes, rivers, streams, and groundwater.
The quality of these water sources varies from area to area, and many water bodies have been deeply polluted by human activity. However, the United States is a developed country with generally good water treatment facilities.
Notwithstanding, the United States faces two important challenges: one is the growing population of the country, which will put more pressure on freshwater sources in the future. The other one is that a few areas of the country are devoid of water supply sources, and they are among the fastest growing regions of the U.S (Nevada, Arizona, New Mexico). This poises a great challenge for U.S. authorities in the near future.
Potential Energy
The potential energy gained is 43750 J
Explanation:
Potential energy is the energy by virtue of an object's position relative to the ground ie, the height of the other object.
For example, an object has more potential energy when it is on top of a two-story building than it does resting on the ground. That's because the object's relative position to the Earth gives it more energy.
Potential Energy is defined as
Potential energy = Mass * height
Given Mass M = 1250 N
Given height h = 35 m
So the potential energy = 1250 * 35 = 43750 J
Thus the potential energy is 43750 J
The appropriate answer is A. Photosynthesis is tied to the carbon cycle because it is the process by which plants use carbon dioxide from the atmosphere to make food. The carbon cycle is essentially the movement of carbon between the biosphere, atmosphere, hydrosphere, and lithosphere. Photosynthesis occurs as an interaction between the atmosphere and the biosphere.
