What is The finished product or waste that forms as a result or process is known as?
output
What type of resources can tidal energy be put?
Tidal power, also called tidal energy, is a form of hydropower that converts the energy of tides into useful forms of power, mainly electricity. Tidal energy is a renewable energy source.
Why does the amount of useful energy decrease as energy changes form?
In any practical machine there is always some loss of energy in its operation, such as losses from an internal combustion engine, or friction in a gearbox, so you never get as much useful output as a straight equivalence of energy would suggest.
What are the different forms of output?
Some common forms of output include text, images, sound, video, and physical output such as printed documents or objects. Each form serves a different purpose and can be used to convey information in various ways.
What is the finished product or waste that forms as a result of a process known as?
output
Why is the amount of useful output energy always less than the input energy?
The reason the useful output energy is always less than the input energy is due to inefficiencies in the energy conversion process. Some energy is always lost as heat, sound, or other forms of energy during conversion, reducing the amount of energy available for useful work. This decrease in useful output energy is described by the concept of energy conservation and the second law of thermodynamics.
What are the differences between useful and wasted energy?
Useful energy is the energy that is converted into a desired form of work or output, such as electricity or mechanical work. Wasted energy, on the other hand, is energy that is not converted into a useful form of work and is typically lost as heat or other forms of inefficiency.
Is energy input usually greater than energy output?
In general, no – energy input is not usually greater than energy output. In a closed system, energy is conserved, meaning that the total amount of energy remains constant. However, in real-world systems, there may be inefficiencies or losses that result in some energy input being converted into forms that are not useful as output.
Why is the output energy of a machine always less than the input energy?
The output energy of a machine is always less than the input energy due to energy losses from factors such as friction, heat, and inefficiencies in the system. These losses result in some of the input energy being transformed into forms that are not useful for the intended function of the machine.
What forms of energy are often produced as useful energy?
Solar Energy
What 2 useful forms of energy come from the sun?
Two useful forms of energy that come from the sun are solar thermal energy, which is used to produce heat, and solar photovoltaic energy, which is used to generate electricity through solar panels.
What is the relationship between an input work and useful output work?
The relationship between input work and useful output work can be represented by efficiency. Efficiency is the ratio of useful output work to input work. A higher efficiency indicates that a larger proportion of the input work is converted into useful output work, while a lower efficiency suggests that more of the input work is wasted or converted into non-useful forms.
What is the efficiency of a machine that miraculously converts all the input energy to useful output energy?
The efficiency of such a machine would be 100%, as all the input energy is converted to useful output energy without any losses. This would be an ideal scenario but is not practically achievable due to factors such as friction, heat dissipation, and other forms of energy loss in real-world machines.
Why is the work output of a machine always less than the work input?
The work output of a machine is always less than the work input due to energy losses in the form of heat, friction, and other inefficiencies. These losses result in some of the input work being converted into forms other than useful output work, leading to a decrease in efficiency.
Why cant a machine put as much energy out as you put in?
Losses of energy within the machine- some of the energy is used up by friction, and converted to heat. There is also the matter of efficency of a machine. The less efficent, the more power you must put in to get the same output.
What is a useful form of energy that can be changed in many different forms?
Electricity is a useful form of energy that can be easily converted into different forms such as light, heat, or mechanical energy. It is versatile and widely used in various applications due to its efficiency and ease of transformation.
Is heat released from every transfer?
Energy always turns from useful energy to less useful forms of energy. so in theory the answer is no, but in reality there is always some heat generated in all transformations.
