Is a contradiction always true?
no it is not always true
Is a tautology always false or true?
Tautologies are always true.
What is an equation called that is not always true?
Seems to me like if it's not always true, then it's no equation.
Are two composite numbers always sometimes or never true?
They are always true - if your calculations are sound.
What is the Formula for calculating the efficiency of a machine?
Efficiency = Output value / Input valueFor example, if a machine needs 10 KW to run and produces 8 KW, its power efficiency is 8/10 = 0.8 or 80%Efficiency is always between 0 and 1 (or 0 and 100 if expressed as a percentage.)
What is true transformation efficiency?
True transformation efficiency is the transformation efficiency at the saturation point, or essentially the highest transformation efficiency that can be attained.
Is it always a good idea to discard low efficiency?
No...... Not always........... They can be modified to high efficiency..............
Is it always a good idea to discard low efficiency devices?
No...... Not always........... They can be modified to high efficiency..............
Is it true that thermal efficiency of a diesel engine equals indicated thermal efficiency - brake thermal efficiency?
no
Is the true efficiency in a heat pump greater or smaller then the efficiency based on the motor?
It is greater. You need to look for the SEER (Seasonal Engergy Efficiency Rating) to see the true engergy rating of the heat pump.
Which of the following statements are true about productive and allocative efficiency society can achieve either productive efficiency or allocative efficiency but not simultaneously?
society can achieve either productive efficiency or allocative efficiency, but not both simultaneously
Why can efficiency never can be 100 percent?
The laws of thermodynamics imply that there will always be some loss of efficiency.
Why a normal machine could not have the mechanical efficiency of 100?
Because there is always going to be friction, the efficiency of any machine will always be less then 100 percent.
Friction is not related to the efficiency of a machine true?
false
Is segmentation is preferred for greater network efficiency?
true
Is it true the energy use for metabolic processes reduces the efficiency of secondary productivity?
TRUE
Do Radiator cover reduces efficiency true or false?
false
