Question 7 10 pts How many tightly bound molecules could a single ray of frequency 2.03 x 1020 Hz break apart? The binding energy of such a molecule is 10 eV. Your answer should be a number with two decimal places in the form: N x 105, indicate only N. E Question 8 10 pts X-ray photons are produced by electrons accelerated through a potential difference of 61 kV. Determine the wavelength of such a photon in nm. Your answer should be a number with four decimal places, do not include unit. 1nm = 10'9 m S
