When a Cs-139 atom with 55 protons undergoes TWO successive beta minus decays, what is the daughter nucleus after the second decay? Cs-139 with 55 protons Xe-139 with 54 protons 1-139 with 54 protons La-139 with 57 protons Ba-137 with 53 protons When Dr. Bruce Banner becomes angry and undergoes a transformation into the Incredible Hulk, his blood plasma becomes saturated with Na-24 atoms. These radioactive sodium atoms decay into stable Mg-24 by beta decay, along with the release of...
Light with a wavelength of 137 nm is shined on the surface of potassium metal. Photoelectrons are ejected from the metal's surface. What is the maximum speed of the ejected photoelectrons? The work function of potassium metal is 2.30 eV. O 7.15E5 m/s 9.51E6 m/s 6.32E5 m/s 8.99E5 m/s O 1.54E6 m/s When Dr. Bruce Banner becomes angry and undergoes a transformation into the Incredible Hulk, his blood plasma becomes saturated with Na-24 atoms.

Question 18 5 pts When Dr. Bruce Banner becomes angry and undergoes a transformation into the Incredible Hulk, his blood plasma becomes saturated with Na-24 atoms. These radioactive sodium atoms decay into stable Mg-24 by beta decay, along with the release of two high-energy gamma rays, to which Dr. Banner is immune. After initially becoming angry and transforming into the Hulk, how long will it take so that only 15% of the Na-24 atoms remain in his blood plasma? The...
