Answer:

B. they have low frequencies because a longer wavelength means that the wave moves slower thus meaning it has a lower frequency.

Answer:

Air always moves from high-pressure places to low-pressure places. This means air moves from denser air to less dense air. This movement of air results in wind. If, for example, there was an area of high-pressure air east of an area of low-pressure air, then the wind would be coming in from the east.

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.

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.

x=1

cross multiply

100x =1000

divide both sides by hundred

therefore x=10

THE PROBLEM

Carbon monoxide (CO)—a colorless, odorless, tasteless, and toxic air pollutant—is produced in the incomplete combustion of carbon-containing fuels, such as gasoline, natural gas, oil, coal, and wood. The largest anthropogenic source of CO in the United States is vehicle emissions.

Explanation:

The incomplete burning of the natural gases petrol or diesel is one of the causes of the creation of carbon monoxide.

It can be defined as the origination of the contaminant substance that poisonous or harmful to our natural environment.

In our environment, pollution can take many different forms depending on the quantity and nature of the contaminant. For instance, the eutrophication process can result in water pollution.

Air pollution persists due to the contaminants present in atmospheric air such as smog.

Land pollution exists because of contaminated soil in the lithosphere.

There are several other types of pollution as well such are sound pollution, radioactive pollution, plastic pollution, oil spill pollution, etc.

When hydrocarbon fuels (such as natural gas, gasoline, and diesel) are burned, carbon monoxide is also produced as a pollutant. The effectiveness of combustion determines the relative amount of CO produced. During their MOT test, older vehicles are inspected yearly for CO emissions. It's interesting to note that only one of the two carbon oxides inhibits combustion; for this reason, carbon dioxide is used in fire extinguishers.

One of the factors contributing to the production of carbon monoxide is the incomplete burning of natural gases such as gasoline or diesel.

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.

Focusing on one specific task

Explanation:

So just focus on one important task. Clear everything else away, and focus on that. By picking your tasks carefully, you're taking care with the container of your time. You can pick important tasks or joyful ones, but you're being conscious about the choices.

I recommend calming down, sitting in a quiet and comfortable space and listening to study music while studying each different subject, one at a time.

Study Music Recommendations:

- Lofi Hip Hop Radio

- MONOMAN

- Fall In Chill

- Ambition

What Subjects To do First Recommendations:

I recommend doing the subjects that are the most easiest for you, once you get the easy ones out of the way, you can spend the rest of your time trying to really learn the hard subjects without having to worry about the other ones!

Fun Fact:

Studying is not just important for educational development, but also builds personal skills. Having good study skills can improve your confidence, competence, and self-esteem. As well as helps reduce stress and anxiety around deadlines and exams.

2. use (a system, procedure, etc.) as an example to follow or imitate.

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.

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.
