22. Consider the case of a radioactive element X which decays by electron (beta) emission with a half-life of 4 days to a stable nuclide of element Z. Which of the following statements is CORRECT? (a) After 8 days the sample will consist of one-fourth element Z and three-fourths element X.

thank u so much！
6. One form of nuclear radiation, beta decay, occurs when a neutron changes into a proton, an electron, and a neutral particle called an antineutrino: n → pt + e + De, where ve is the symbol for an antineutrino. When this change happens to a neutron within the nucleus of an atom, the proton remains behind in the nucleus while the electron and neutrino are ejected from the nucleus. The ejected electron is called a...

8. Consider the structure of beta-carotene: H₃C CH₃ CH3 CH3 CH3 I. CH₃ CH3 CH3 CH3 CH3 It is a linear polyene in which 21 bonds, 10 single and 11 double, alternate along a chain of 22 carbon atoms. Assume that beta-carotene can be modeled as a one-dimensional box or pipe with each of the 21 bonds having a length of 1.4x10-10 m. Assume that there is one freely moving electron in the n=11 energy level that can be promoted...

A beam of protons with various speeds is directed in the positive x direction. The beam enters a region with a uniform magnetic field of magnitude 0.49 T pointing into the page, as shown below. It is desired to use a uniform electric field (in addition to the magnetic field) to select from this beam only those protons with a speed of 1.23 105 m/s; that is, only these protons should be undeflected by the two fields. (a) Determine the electric...
