3rd: -2.89 eV 2nd: -7.27 e'v' Ground state: 43.93 eV What is the wavelength of a photon released when an electron moves from the 3rd energy level to the ground state? Round and record your answer to the nearest nanometer (nm). Your Answer: 113 Answer Question 2 {1 point} J Saved Alpha particles travel undeflected through magnetic and electric fields that are perpendicular to each other. The speed of the alpha particles is [4.52103-{10'5} mfs and the strength of the magnetic field is (1.5?)(105-1} T. What is the electric field strength? Note: Your answer is assumed to be reduced to the highest power possible. C] 110 3:10 Your Answer: Answer Question 3 {1 point} J Saved A mass spectrometeris used to identify the number of Unranium-235 in a radioactive sample. If a Uranium-235, with a charge of 3.20 x1049 C, passes through a uniform magnetic field of [1.522x10\"3} T at a perpendicular speed of {4.63xlOA4] mz's, what is the radius [in m} of deflection of Uranium-235 in this magnetic field
