Review Constants In proton-beam therapy, a high-energy beam of protons is fired at a tumor. The protons come to rest in the tumor, depositing their kinetic energy and breaking apart the tumor's DNA, thus killing its cells. For one patient, it is desired that a total of 0.15 J of proton energy be deposited in a tumor. To create the proton beam, the protons are accelerated from rest through a 20 MV potential difference. How many protons must be fired at the tumor to deposit the required energy? Express your answer to three significant figures. ► View Available Hint(s) 190 ALOR O ?

Review Part A In proton-beam therapy, a high-energy beam of protons is fired at a tumor. The protons come to rest in the tumor, depositing their kinetic energy and breaking apart the tumor's DNA, thus killing its cells. For one patient, it is desired that a total of 0.15 J of proton energy be deposited in a tumor. To create the proton beam, the protons are accelerated from rest through a 20 MV potential difference. How much kinetic energy, in electronvolts, does one proton have after being accelerated? Express your answer to three significant figures. View Available Hint(s) 10 AZN 0 0 ?
