Alight detector (your eye) has an area of 1.95×10-6 m2 and absorbs 75% of the incident light, which is at wavelength 500 nm. the detector faces an isotropic source, 3.40 m from the source. if the detector absorbs photons at the rate of exactly 3.950 s-1, at what power does the emitter emit light?

The membrane surrounding a living cell consists of an inner and an outer wall that are separated by a small space. assume that the membrane acts like a parallel plate capacitor in which the effective charge density on the inner and outer walls has a magnitude of 7.0 × 10-6 c/m2. (a) what is the magnitude of the electric field within the cell membrane? (b) find the magnitude of the electric force that would be exerted on a potassium ion (k+; charge = +e) placed inside the membrane.
