What do visible and invisible energy compose?
Visible and invisible energy compose dark energy or radiation. Radiation is composed of both visible and invisible light or energy that expands or spreads as it moves away from its source.
What things are in the back of a wind turbine?
There are a few things on the backs of Wind Turbines: 1) Anemometers - wind speed sensors that help the turbine fine tune its blade pitch to be most efficient. 2) Wind Vanes - wind direction sensors that keep the turbine lined up with the wind, or turn it away from the wind when the gusts are too strong and can damage the turbine. 3) Visibility Lighting - red and white lights to meet requirements of aviation authorities for visibility.
How is hydroelectric energy gathered and or created?
Hydro-power usually starts with a dam. A controlled amount of water is led away from the dam , and on to a water wheel, also called a turbine. The force of the running water gets the turbine spinning. The turbine is hooked up to an electrical generator which produces electricity as it turns. the electricity is then fed into the electrical grid and makes its ways out to homes and industries.
What will happen to the size of the shadow if the object moves away from a tilted source of light?
The shadow will get longer.
What happens if a source of light is moved away from the focus of a parabolic reflector?
Then the focused beam is no longer parallel, and is spreads faster from the axis as it proceeds away from the reflector.
What do you mean of offshore?
Offshore simply means away from shore. It means overseas or outside your country.
What is called offshore?
Offshore means to be away from the coast. For example: There are several oil-rigs working in the North Sea, just offshore from Aberdeen, Scotland.
Why does the sun look like it is following us?
Objects that are further away stay visible for a longer period of time.
What do the words island offshore refer to?
The words island offshore refer to a island that is away from the coast. In general this term applies to banking that gets done out of the country also called offshore.
What does it mean if a star is experiencing a red shift?
redshift is what happens when visible light gets longer in wavelength, thus shifting toward the red end of the spectrum of visible light. This is a phenomenon that occurs when the light source is moving away from the observer.
What is the function of a wastegate valve?
The function of the wasegate valve is to divert exhaust gases away from the turbine in the engine system. This enables it to control the speed of the turbine.
What are the dangers of offshore and onshore winds?
Offshore winds will blow the unwary captain onto shoals or reefs. Onshore winds will blow the unwary captain away from his next landmark or landfall.
What is the position of the shaft in pelton turbine?
In the center of the wheel shaft is connected to the spoon away.
What are the advantages and disadvantages of floating offshore windmill?
Anyone who looks at a wind atlas can see one obvious advantage of offshore wind turbines compared to any other location: there is more power in the wind offshore than just about anywhere else in the world. Another advantage to offshore wind turbines is that many of the places that use the most power -- large cities -- are relatively close to shoreline, and far away from other areas of high wind power potential -- the high mountain plateaus. One disadvantage of a floating offshore wind turbine is that there is the risk that bad weather may make it completely disappear, as happened to the Project Mustard Seed turbines. With land-based wind turbines, there is generally *something* left to salvage no matter how bad the weather gets. ... please fill in other advantages and disadvantages ...
Why is The moon surface visible to an observer on earth?
Its surface is visible because of how AU's (Astronomical Units) it is away from the Earth.
Why does the Moon's surface is visible to an observer on earth?
Its surface is visible because of how AU's (Astronomical Units) it is away from the Earth.
Some stars might no longer be in existence but you still see them in the night sky why?
Stars that are no longer in existence, or dead stars, may be still visible in the night sky depending on how far away the star was from earth. Light takes time to travel, so if a star is 50 billion lightyears away from earth, and it died 25 billion years ago, due to the amount of time it takes for the light to reach our eyes, the star's light will still be visible for another 25 billion years.
