For this question, CHOOSE THE CORRECT ANSWER, then explain your reasoning in the RATIONALE section below: Alpha,
Beta-plus, Beta-minus and Gamma decay are all different forms of radio-Active decay. A certain radio-isotope emits ONE
alpha particle, and its products then emit TWO beta-minus particles in succession. The atomic number of the final resulting
nucleus will now change (as compared to your starting nucleus) by
O A. zero
O B. minus 1
OC. minus 2
O D. minus 3
Write solution detailed solution (Given, Unknown, Formula, Step-by-Step Solution). Box your final answer. Please make sure that your handwritten is readable. Thank you.
ONLY ANSWER 3 AND USE OTHER QUESTIONS FOR CONTEXT
Suppose we have two sources of light, a deep red one with wavelength 700 nm, and a violet one with wavelength 400 nm. Both produce the same optical power, delivering 1 milliwatt (10−310−3 watts) of energy per second per square centimeter to a metal target with an area of 1cm2 located 1 meter from the sources.
1. Which color would deliver more photons each second?
All the photoelectrons that are produced from the light are presumed to be collected by another electrode and we determine the current in amperes using a circuit and an "ammeter", that is, some device that can give a precise quantitative measure of the current. Such a device might use the magnetic field generated by the current, or the voltage produced when the current flows across a resistance.
2. If the work function of the surface is 2 eV, will we see a current with both colors, one color, or neither one? If so, how much (in amperes), or if not, explain.
3. If we now…
