Which of these reactions requires a net input of energy from its surroundings?
An endergonic reaction requires a net input of energy from its surroundings. This is because the energy needed to drive the reaction forward is greater than the energy released during the reaction.
In a positive feedback system how does the output affect the input?
In a positive feedback system, the output enhances or amplifies the input that started the process, causing a self-reinforcing loop. This means that an increase in the output leads to an increase in the input, continuing to drive the system further in the same direction.
What are the 3 main characteristics of a function?
Each input has only one output. The same input will always produce the same output. The function can be represented by an equation or a graph.
Is an finger print input or output?
A fingerprint is an input. It is a biometric input used for security purposes by scanning and capturing unique patterns on an individual's finger to authenticate their identity.
What is an input and output for photosynthesis?
It changes constantly, there is no set output. The energy a plant gains from photosynthesis comes from light, so the energy produced changes with more/less sunlight. Also, availability of water, availability of carbon dioxide, temperature and the species of plant are all factors which will effect this. eg. A large oak tree on a bright sunny day will produce a large amount of energy, while on a cold rainy dark day a small holly bush will produce a little energy. Photosynthesis and the energy produced is not a linear process; it chsngrs each time due to all the contributing variables. And by the way, this should be in biology not physics...
Is it possible for energy output to be greater than energy input?
No.
Is work output greater than work input?
No, work output can never be greater than work input according to the principle of conservation of energy, which states that energy cannot be created or destroyed, only transformed from one form to another. In any system, the work input will always be equal to or greater than the work output.
Why is input energy more useful than output energy?
Input energy is typically more useful than output energy because input energy is the initial energy put into a system to produce the desired output. Output energy, on the other hand, is the energy produced by the system after losses and inefficiencies have occurred, so it is usually less than the input energy. By maximizing input energy efficiency, we can achieve a more effective output.
What are the comparison of energy output with energy input?
Energy output refers to the amount of usable energy obtained from a system, while energy input is the amount of energy required to operate that system. A system is considered efficient when the energy output is greater than the energy input. Conversely, inefficiency occurs when more energy is put into a system than what is obtained as output.
What is the relationship between energy input energy output and energy losses whenever transfer of energy takes place?
Energy input = energy output + losses. Both energy output and losses are usually positive (they might also be zero in some specific cases), meaning that (usually) each of them individually is less than the energy input.
Why it is impossible to have output greater than work input?
Whenever we do any work some energy will be converted into any form other than the actual input energy for the work to be done so it is impossible to have the output greater than work input example : some energy will be converted to heat energy due to friction
Can you make work output of a machine greater then the work input?
No. And you cannot make it greater THAN the input, either.
Can you make work output on a machine greater than work input?
No, it is impossible to have work output greater than work input because of the conservation of energy principle, which states that energy cannot be created or destroyed, only transformed. Therefore, the work output of a machine will always be less than or equal to the work input.
Can you make the work output of a machine greater then the work input?
No - that would violate Conservation of Energy. So far, there is no known process that violates Conservation of Energy, and it doesn't seem likely that one will ever be found.
What is the relationship between efficiency useful energy output and total energy output?
Efficiency is the ratio of useful energy output to total energy input. A higher efficiency indicates that a greater proportion of the total energy input is being converted into useful energy output. Therefore, as efficiency increases, the amount of useful energy output relative to total energy output also increases.
Why is it impossible for the output work of a machine to be greater than the machine's input work?
The output work of a machine can never be greater than the input work because of the law of conservation of energy, which states that energy cannot be created or destroyed in an isolated system. Any energy input into a machine must be accounted for in the output work, so the output work cannot exceed the input work.
What is a comparison of a machine's work output and work input?
Output is always greater than input. The output is multiplied from input.
