Answer: C: no change in motion
Explanation:
If two forces are balanced, the net force is 0, which is neither positive nor negative. there will thus be no change in motion
Explanation- balanced forces are equal in size and opposite in direction when forces are balanced there is no change in motion. For example, if you were to push or pull an object from opposite directions but with the same force. The object will not move.

The creation of carbon monoxide is an effect. What is one cause?
Answers
Answer:
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.
What is pollution?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.

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. What would the research question be for this team?
Which angle converts the largest percentage of potential energy from the wind into kinetic energy of the turbine?
Which angle converts the largest percentage of kinetic energy from the wind into kinetic energy of the turbine?
Which angle converts the largest percentage of potential energy from the wind into potential energy of the turbine?
Which angle converts the largest percentage of kinetic energy from the wind into potential energy of the turbine?
Answers
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.
What is Mechanical energy?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.

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.

The turbines can be seen inside this hydroelectric dam. Why are they located at that particular height?
(1 point)
There is a small drop, so the water will still have a lot of kinetic energy to transfer to the turbine.
There is a large drop, so the water will have a lot of kinetic energy to transfer to the turbine.
There is a large drop, so the water will have a lot of potential energy to transfer to the turbine.
There is a small drop, so the water will still have a lot of potential energy to transfer to the turbine.
Answers
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.
How is the energy transformed in the hydroelectric dam?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.

Explanation:
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.
Answers
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.
