Which statement describes how rays behave when they travel through media during reflection and refraction? during refraction, rays stay in the original medium, and during reflection, rays pass into a new medium. during reflection, rays stay in the original medium, and during refraction, rays pass into a new medium. during reflection and refraction, rays stay in the original medium. during reflection and refraction, rays pass into a new medium.

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.
