Can energy be measured
WebEnergy expenditure is measured by indirect calorimetry or calculated using mathematical equations. Indirect calorimetry determines energy expenditure by measuring the body's oxygen consumption and carbon dioxide production using a computerized metabolic cart. 28, 29. Energy expenditure can be calculated by using the Harris-Benedict equation. WebAssuming that the total vacuum energy associated with these fluctuations cannot exceed the presently measured dark energy of the universe, we predict an upper cutoff frequency ofνc=(1.69 ± 0.05)×1012Hz for the measured frequency spectrum of zero-point fluctuations in the Josephson junction.
