The Argon ( ion laser has a strong lasing emission at 488 nm The laser tube is 1 m in length, and the bore diameter is 3 mm The output power is 1 W Assume that most of the output power is in the 488 nm emission Assume that the tube end has a transmittance T of 0 1 Calculate the photon output flow (number of lasing photons emitted from the tube per unit time), photon flux (number of lasing photons

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.
