PLS HELP BIG GRADE 5. Water stored in a reservoir is used to generate electricity as it flows down and into a river. The river flows to the ocean, where it evaporates to form clouds. Rain falls from the clouds into streams that flow into the reservoir. Which location of the water has most potential energy? Assume the amount of water in each place is the same. These are the locations: 1. where it enters the river from the reservoir, 2. when it is in the ocean, 3. when it is in the reservoir, and 4. when it is in the clouds.
1. Where it enters the river from the reservoir.
2. When it is in the ocean.
3. When it is in the reservoir.
4. When it is in the clouds.
Explain your answer.

Water falls from a reservoir through a channel to a turbine. The water turns the turbines, which allows the generator to make electricity.

Explanation: Hydroelectricity can be defined as the generation of electricity by utilizing the speed of water stream in a reservoir of water. The high speed water current is used to move the water turbine the energy produced in the turbine can be used to generate electricity by the generator.

the element that provides strength to the exoskeletons of clams and oysters is phosphorus. this is so because calcium carbonate is the main component in the shells.

explanation:

oxygen is the first element in group 16 (via) of the periodic table. the periodic table is a chart that shows how chemical elements are related to each other. the elements in group 16 are said to belong to the chalcogen family. other elements in this group include  sulfur, selenium, tellurium,  and  polonium.  the name chalcogen comes from the greek word  chalkos,  meaning "ore." the first two members of the family, oxygen and sulfur, are found in most ores.

oxygen is by far the most abundant element in the earth's crust. nearly half of all the atoms in the earth are oxygen atoms. oxygen also makes up about one-fifth of the earth's atmosphere. nearly 90 percent of the weight of the oceans is due to oxygen. in addition, oxygen is thought to be the third most abundant element in the universe and in the solar system.
