WebbThe constant is equal to approximately 8.854 x 10 -12 F/m ( farad per meter), with a relative standard uncertainty of 1.5 x 10 -10. A farad is a standard unit of capacitance that indicates the ability of a substance to hold an electric charge. The substance in this case is the vacuum. Figure 1. The vacuum permittivity equation. Webb30 apr. 2024 · The specific rate constant ( k) is the proportionality constant relating the rate of the reaction to the concentrations of reactants. The rate law and the specific rate constant for any chemical reaction must be determined experimentally. The value of the rate constant is temperature dependent.
WebbDirect variation. The phrase “ y varies directly as x ” or “ y is directly proportional to x ” means that as x gets bigger, so does y, and as x gets smaller, so does y. That concept can be translated in two ways. for some constant k. The k is called the constant of proportionality. This translation is used when the constant is the ... Webb22 dec. 2024 · The equation for elastic potential energy relates the displacement, x , and the spring constant, k , to the elastic potential PE el, and it takes the same basic form as the equation for kinetic energy: PE_ {el}=\frac {1} {2}kx^2 P E el = 21kx2 As a form of energy, the units of elastic potential energy are joules (J).
