In a positive feedback system how does the output affect the input?
In a positive feedback system, the output increases the input.
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...
Define Ecosystem in terms of inputs and outputs?
define output and input ecosystem/
When is acetyl CoA produced?
During pyruvate processing
Which of these reactions requires a net input of energy from its surroundings?
Endergonic
Is it possible for energy output to be greater than energy input?
No.
Is work output greater than work input?
No. Work output is less than or equal to work input. Since some energy (work) is lost in most processes, it will usually be less.
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.
What kind of energy does a toster have?
Input energy: usually electric energy. Output energy: heat.
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
Is energy input greater than energy output?
Yes, because there is always a small loss of energy within the system.
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.
If a machine has a mechanical advantage much greater than 1 how will the output force be in comparison to the input force?
The Output Force Will Most Likely Be Greater Than The Input Force. So "OUTPUT" Is Greater Than "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.
The output force of a rake is greater than the input force?
Yes, the output force of a rake is greater than the input force.
What is the relationship between energy input and energy output and energy losses whenever transfer of energy takes place?
Input energy = output energy + losses
How is energy efficiency determined?
You divide useful output energy by the input energy. Or equivalently, useful output power by input power.
