In an a scattering experiment, the area of the a particle detector is 0.50 cm². The detector is located 10 cm from a 1.0-μm-thick silver foil. The incident beam carries a current of 1.0 nA, and the energy of each a particle is 6.0 MeV. How many a particles will be counted per second by the detector at
