How do chemical changes affect our everyday life?

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.

How much energy is supplied to each coulomb of charge that flows through a 12-v battery?

Each line (unit) on the horizontal axis represents: 5 years 10 years 20 years all of the above
