Why can't the efficiency of a device or a process be greater than 100?
Efficiency cannot be greater than 100% because efficiency measures energy, and since energy is not made, only transfered (conservation of energy) then we cannot gain energy. Hence the energy out must be at most the energy in. Thus efficiency can be at most 100%
How do you convert the photometric unit to radiometric unit?
There is no direct conversion because they are used to measure two different things. Radiometric units are used to measure radiant energy across the entire spectrum, whereas photometric units are used to measure visible light as preceived by the human eye. As the eye's sensitivity varies across the visible spectrum (being most sensitive to green light, and least sensitive to red and violet light), the conversion between the two systems of measurement varies according to wavelength at which it they are being compared.
How do the energy and the most probable location of an electron in the third shell of an atom compare to the energy and the most probable location of an electron in the first shell of the same atom?
in the third shell, an electron has more energy and is further from the nucleus
Which branch of mathematics does kenic energy and most other science equations most strongly rely on?
Calculus
What word has a meaning that is most closely related to the word expeditious?
Efficient. Although "expeditious" carries the meaning of doing something quickly as well as efficiently.
