In proton bean therapy, a beam of high-energy protons is used to kill canerous cells in a tumor. In one system, the beam, which consists of protons with an energy of 2.8×10^−11J, has a current of 80 nA.The protons in the beam mostly come to rest within the tumor. The radiologist has ordered a total dose corresponding to 3.8×10^−3 J of energy to be deposited in the tumor. Part A How many protons strike the tumor each second? Express your answer as a number of protons.
