The correct answer is; Water flowing downstream is held up in a reservoir behind a dam. Some water moves down channels through turbines connected to generators which produce electricity.
Further Explanation:
Hydroelectric power is being used more in recent times than in the past. Hydroelectric power is a more cleaner energy source than the coal plants that produce electricity.
Hydroelectric power plants are built within a dam system and uses the water as source of energy. The water goes into channels created that hits the turbines, the turbines are then moved around by the water and these are connected to the large generators and this produces electric. There are many new hydroelectric plants being built. One of the newest hydroelectric power plants is located in Pella, Iowa.

Answer:
2.33×10¯¹⁶ g of forsterite
Explanation:
From Avogadro's hypothesis, we understood that 1 mole of any substance contains 6.02×10²³ atoms. This equally means that 1 mole of forsterite (Mg2SiO4) contains 6.02×10²³ atoms.
1 mole of forsterite (Mg2SiO4) = (24×2) + 28 + (16×4)
= 48 + 28 + 64
= 140 g
Finally, we shall determine the mass of forsterite that contains a million oxygen atoms.
140 g of forsterite (Mg2SiO4) contains 6.02×10²³ atoms.
Therefore, Xg of forsterite (Mg2SiO4) will contain 1×10⁶ atoms of oxygen i.e
Xg of forsterite (Mg2SiO4) =
(140 × 1×10⁶) /6.02×10²³
= 2.33×10¯¹⁶ g
Therefore, 2.33×10¯¹⁶ g of forsterite contains a million oxygen atoms..
