values from Table 7.1, how many DNA molecules could be broken by the energy carried by a single electron in the beam of an old-fashioned TV tube? (These electrons were not dangerous in themselves, but they did create dangerous x rays. Later model tube TVs had shielding that absorbed x rays before they escaped and exposed viewers.)
Step-by-step solution Step 1 of 1 The number of DNA molecules that can be broken by the energy of one electron is . Substitute for and for in the above equation. Therefore, Therefore, the number of DNA molecules that can be broken by the energy of one electron is .
