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.

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.

Answer: scissors and a axle.

Explanation:

Answer:

A. transfer energy from one point to the other

Explanation:

When waves transfer energy, the matter doesn't move with it, so the energy goes from one point to the other. You can see this more clearly on a transverse wave example.

Explanation:

[tex]d = v \times t[/tex]

[tex]v= \frac{d}{t} = \frac{33}{1.5 \times 60} = \frac{33}{90} = 0.3666 \: meters \: per \: sec[/tex]

Answer: The answer is number is two

Explanation: Because as it says there is a large drop, so the water will still have a lot of kinetic energy to transfer to the turbine.

In the hydroelectric dam, there is a large drop, so the water will have a lot of potential energy to transfer to the turbine. Therefore, option (C) is correct.

In the hydroelectric dam, electric energy is generated using water from a turbine. The flowing water is utilized to propel the turbines. At first, a huge amount of the flowing water has stored across the dams. The kinetic energy of flowing water is stored in the form potential energy in the dams.

Then the stored water in the dam will fall on the turbines so that the turbines are placed in the deep and rotate the turbines and the potential energy of water to the turbines which converted into mechanical energy.

Then the turbines rotate and generate electricity and the mechanical energy is transformed into electrical energy.

Therefore, turbines in the hydroelecric dams are located at particuler height.

The type of stars that is the hottest 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.

Answer:it would be which angle converts the most potential energy to into kinetic energy of the turbine

Explanation:

The best research question would be finding the angle that converts the largest percentage of kinetic energy from the wind into kinetic energy of the turbine.

Mechanical energy is the sum of kinetic and potential energy of the body. Mathematically -

E[M] = E[K] + E[P] = 1/2mv² + mgh = m(1/2v² + gh)

Given is a team of engineers is working with a wind turbine. The team is working with a model and testing different angles for the blade of the wind turbine.

Flowing wind carries very small particles and other light components it finds in its way. The sum of the kinetic energies of these individual particles and components are responsible for the kinetic energy of the flowing wind. Now, this wind is utilized to rotate the turbine blades and generate electricity. In this process, the kinetic energy of the wind does work on the blades of the turbine such that the amount of work done causes the blades to rotate. Now, the rotating blades will have rotational kinetic energy. For a mathematical model -

E[wind] = E[blades]

1/2mv² = 1/2Iω²mv² = Iω²

mv² - Iω² = 0

Hence, the total energy remains conserved.

Therefore, the best research question would be finding the angle that converts the largest percentage of kinetic energy from the wind into kinetic energy of the turbine.
