Silver contains 5.8 * 1028 free electrons per cubic meter. At absolute zero, what is the speed of an electron with this energy?
8. A white dwarf is a very dense star, with its ions and electrons packed extremely close
together. Each electron may be considered to be located within a region of size x= 1.5 x
10-12 m. Estimate the minimum speed of the electron. Do you think that the effects of
relativity will be important for these stars?

- Questão 5 Quantum tunneling was applied in 1928 by physicist George Gamow (and others) to explain the alpha emission of nuclear radiation, as we will see in the topic of nuclear physics. The alpha particle, whose mass is m = 6.64 x 10^(-27) kg, remains attached to the nucleus due to a strong interaction with the other nuclear constituents (nucleons) which overcomes the electrostatic repulsion between them, resulting in a graph of potential energy shown in figure A, where R is the range of the strong force and is of the order of the nuclear radius. However, note that there may be states for the alpha particle with energy E > 0 that can “tunnel” the Coulomb potential barrier. Consider a one-dimensional approximation for the potential energy well of an alpha particle in a 15 fm wide Uranium core (equivalent to the core diameter), in which the Coulomb barrier was modeled as a 20 fm wide rectangular barrier and 30 MeV high (see figure B). Knowing that the longest de Broglie wavelength…arrow_forwardAn proton is confined within a region of width 3.22 x 10-¹1 m. What is the minimum kinetic energy of a proton? A. 41.66 J.
