Describe a ways car manufacturers try to reduce drag and why.

Answers

Aerodynamic drag can be reduced by altering the density of the air and the vehicle speed, but these factors are not easily controlled. Instead, to reduce drag, car manufacturers can make the height and width of the front of the car smaller. ... This shape reduces drag and the forces that try to propel the car backwards

Aerodynamics is a way to reduce drag that uses car manufacturers.

What is aerodynamic ?

Aerodynamics is the motion of the air. airplane flies cause of aerodynamics.

Aerodynamics is the study of forces that are resulted by motion of the air.

To reduce the aerodynamic drag further, the manufacturers use character lines on the exteriors of the car's body right from its concept stage. These lines help the air to pass smoothly over the body and thus, reducing the air resistance.

cars have flat vertical face in front. When it moves through air, drag force directly proportional to the velocity applies on the car which opposes motion of the car. after studding aerodynamics when we make triangular like shape to the front body of the car, it cuts the air and front air goes from side of the car which reduces oppose to the motion, and car can have more speed.

What function does a generator perform inside a power plant?A.The generator stores electrical energy for later use in homes and businesses.

B.The generator transforms the mechanical energy of the turbine into electrical energy.

C.The generator spins the turbine to create mechanical energy.

D.The generator spins the turbine to create electrical energy.

Answers

The generator is called a 'generator' because it 'generates' something
that wasn't there before.

The power plant uses water, steam, or wind, to spin a turbine, and
the generator transforms the mechanical energy of the turbine into
electrical energy (which wasn't there before).        (Choice-B)

B. The generator transforms the mechanical energy of the turbine into electrical energy.

Note that a generator uses mechanical energy to turn the wire loop in the magnetic field. This causes electric current to flow, creating electrical energy.

Opponents of rent control believe that it causes _____.

Answers

Housing shortage is the right answer.

Rent control ordinances are a collection of laws that direct or prevent a landowner from increasing rents. While an obviously good means of ruling landlords and managing affordable accommodations, rent control is not a completely approved idea. Those who object with rent control list various reasons for their opposition. Critics of rent control hold that the regulations defend old tenants at the expense of new tenants. They contend that because the administration commands a price ceiling on the home the quality and quantity of accessible housing decays.

Which of the following best describes the fate of energy in ecosystems?

Answers

The fate of energy in ecosystems is for it to be lost as heat. Energy "flows" through the ecosystem in the form of carbon-carbon bonds. When respiration occurs, the carbon-carbon bonds are broken and the carbon is combined with oxygen to form carbon dioxide. This process releases the energy, which is either used by the organism (to move its muscles, digest food, excrete wastes, think, etc.) or the energy may be lost as heat.All energy comes from the sun, and that the ultimate fate of all energy in ecosystems is to be lost as heat.

Answer:

It's best to also include the options since this is a multiple choice question! But the best answer would be D.

Explanation:

It flows through and is used by ecosystems.
