Adental x-ray typically affects 214 g of tissue and delivers about 3.8 μj of energy using x-rays that have wavelengths of 0.026 nm. what is the energy ephoton, in electron volts, of x-ray photons? how many photons are absorbed during the dental x-ray? assume the body absorbs all of the incident x-rays.

Which of the following best describes internal energy? a. the difference between the kinetic and potential energies of the particles in a system b. the sum of the kinetic and potential energies of the particles in a system c. the sum of the kinetic and thermal energies of the particles in a system d. the difference between the kinetic and thermal energies of the particles in a system
