Radio waves from a source are incident on a flat surface at normal incidence. If the surface absorbs 100% of the incident energy and experiences a pressure of 3.45 x 10-7 N/m, what was the power per unit area of the incident waves? W/m Submit Answer 7. [-/1 Points] PRACTICE ANOTHER A 15.0 mW laser beam is directed toward a small sphere of diameter 1276 nm and density 6.00 x 10 kg/m. The beam's focusing is adjusted until the cross section of the beam is the same as the sphere's diameter. If the sphere absorbs 100% of the incident energy, calculate the magnitude of the acceleration of the sphere due to the radiation force it experiences from the beam.
