how
did we get the following equation (1.9) from maxwells
equations
at e at where p is the density of free charges and j is the density of currents at a point where the electric and magnetic fields are evaluated. The parameters and are constants that determine the property of the vacuum and are called the electric permittivity and magnetic permeability respectively The parameter c-1/olo and its numerical value is equal to the speed of light in vacuum,c 3 x...
BACKGROUND The first part of this assignment focuses on the thermodynamics of enzyme-catalysed reactions. To answer the questions posed you will need apply the following two equations. Note that you may need to re- arrange these equations to determine the value you need. You also need to take care with the units of the values you use and determine. The first equation defines the relationship between the change in free energy (AG ") and the equilibrium between the products and...
