C ,The amount of water released through the dam and the dam's height account for the potential energy.
<u>Explanation:</u>
Hoover dam in Nevada generate the electricity by the hydroelectric power . it is the form of energy. Its provides 96% of the renewable energy in the united states : it power comes from the water. When the water is falling on the turbine it experience the force of gravity.
It is used to turn turbine and generators that produce electricity; to generate electricity the water is in motion, it experiences the potential energy. When the blades turns it experiences the mechanical energy then into form to electrical energy. The potential energy is depends on the two factors that is mass of the dam and the height of the dam.
Combustion is the burning of a substance. It could be complete or could be incomplete. It changes the form of carbon and so it plays it's role in cycle
The best thing to do is to rinse the dust cap with freshwater and dry it with a clean towel of air from the tank. Be sure to blow or towel dry the dust cap before putting it in place on the first stage.
The answer is dependent variable.
Answer:
8900 CFU/mL
Explanation:
Colony Forming Units (CFU) is a value that indicates the degree of microbiological contamination of an environment. It expresses the relative number of microorganisms of a given taxon in a volume of one cubic meter of water.
UFC is the minimum number of separable cells on the surface, or inside, of a semi-solid agar medium that results in the development of a visible colony of the order of tens of millions of descending cells. The CFUs can be pairs, chains or clusters, as well as individual cells. Colony forming unit.
Calculation
Colonies * Dilution = CFU/mL
89 * (100/ 1 mL) = CFU/mL
8900 CFU/mL
