Which statement correctly identifies the relative levels of kinetic and potential energy in a hydroelectric dam?
Kinetic and potential energy are both highest at the bottom.
Kinetic and potential energy are both highest at the top.
Kinetic energy is highest at the top; potential energy is highest at the bottom.
Kinetic energy is highest at the bottom; potential energy is highest at the top.
Answer:
the answer is the third question
Explanation:
because while the water is behind the dam it has potential energy and while it goes down it stores up kinetic energy then generators convert all the energy into electricity and that is one source that makes power
Kinetic energy is highest at the bottom; potential energy is highest at the top, therefore the correct answer is option D.
What is mechanical energy?
As total mechanical energy is the sum of all the kinetic as well as potential energy stored in the system.
ME = KE + PE
As given in the problem we have to find out which statement correctly identifies the relative levels of kinetic and potential energy in a hydroelectric dam,
The total mechanical energy of the water in a hydroelectric dam is the sum of the kinetic energy and the potential energy which interconvert into each other.
Thus, Kinetic energy is highest at the bottom; potential energy is highest at the top, therefore the correct answer is option D.

Which of the following types of stars is the hottest? (2 points)
Group of answer choices
Blue main sequence
Orange main sequence
Red supergiant
White dwarf
The type of stars that is the hottest is Blue main sequence.
What is Blue main sequence?
An O-type principal grouping star (O V) is a fundamental succession (center hydrogen-consuming) star of unearthly sort O and glow class V. These stars have somewhere in the range of 15 and multiple times the mass of the Sun and surface temperatures somewhere in the range of 30,000 and 50,000 K.
Their temperature range is so high. So, the hottest star is blue main sequence.
