Energy density of wax6/1/2023 The intensive properties cv and cp are defined for pure, simple compressible substances as partial derivatives of the internal energy u (T, v) and enthalpy h (T. What is the combined energy density of the electric and magnetic fields?Answer: First we calculate the density and energy of each field, finally we add the densities to obtain the total energy density, where B = 3.10 -2T, E = 9.10 7V/m, ε = 8.85.10 -12C 2/N.m 2 and μ = 4π.10 -7N/A 2.U E = εE 2/2U E = 8.85.10 -12C 2/Nm 2.(9.10 7V/m) 2/2U E = 35842.5J/m 3U B = B 2/2.μU B = (3.10 -2T) 2/2.4π.10 -7N/A 2U B = 358.1J/m 3U = U E+U BU = 35,842.5J/m 3+358.1J/m 3U = 36200.6J/m 3 Related Links:Energy Density Formula. Specific heat, or specific heat capacity, is a property related to internal energy that is very important in thermodynamics. What is the combined energy density of the electric and magnetic fields?Answer: First we calculate the density and energy of each field, finally we add the densities to obtain the total energy density, where B = 5.10 -3T, E = 3.10 6V/m, ε = 8.85.10 -12C 2/N.m 2 and μ = 4π.10 -7N/A 2.U E = εE 2/2U E = 8.85.10 -12C 2/Nm 2.(3.10 6V/m) 2/2U E = 39.825J/m 3U B = B 2/2.μU B = (5.10 -3T) 2/2.4π.10 -7N/A 2U B = 9.95J/m 3U = U E+U BU = 39.825J/m 3+9.95J/m 3U = 49.775J/m 3.2) In a certain region of space, the magnetic field has a value of 3.10 -2T, and the electric field has a value of 9.10 7V/m.
