Web12 de abr. de 2024 · According to Joule’s law, the amount of heat generated is proportional to the resistance of the wire, the time duration for which the current flows, and the square of the current flowing through the circuit. The mathematical equation explaining Joule’s law of electric heating can be given by: Q = I 2 Rt. Q is the amount of heat generated in ... WebNote that 1 eV is the kinetic energy acquired by an electron or a proton acted upon by a potential difference of 1 volt. ... So 1 eV = (1.6 x 10^-19 coulombs)x(1 volt) = 1.6 x 10^-19 Joules. Now let's calculate the frequency of the 1 eV photon. E = hf, so f = E/h. Hence, ...
Web14 de ene. de 2024 · Convert the mass to kilograms: m = 235 × 1.66×10⁻²⁷ kg = 3.9×10⁻²⁵ kg. Evalue the mass that converts to energy: Δm = 0.1% × 3.9·10⁻²⁵ kg = 3.9×10⁻²⁸ kg. Multiply it by the squared speed of light, c² = 9×10¹⁶ m²/s². The resulting energy equals about 3.51×10⁻¹¹ J or 219 MeV. What is the mass deficit for the D-T fusion reaction? Web12 de sept. de 2024 · An electron in a metal can be modeled as a wave. The lowest energy corresponds to the largest wavelength and smallest quantum number: nx, ny, nz = (1, 1, 1). Equation 9.5.3 supplies this “ground state” energy value.
