67. BIO Predict/Calculate Cell Membranes The membrane of a liv- ing cell can be approximated by a parallel-plate capacitor with plates of area 4.75 × 10-⁹ m², a plate separation of 8.5 × 10-⁹ m, and a dielectric with a dielectric constant of 4.5. (a) What is the energy stored in such a cell membrane if the potential difference across it is 0.0725 V? (b) Would your answer to part (a) increase, decrease, or stay the same if the thickness of the cell membrane is increased? Explain.
Dielectric Constant Of Water
Water constitutes about 70% of earth. Some important distinguishing properties of water are high molar concentration, small dissociation constant and high dielectric constant.
Electrostatic Potential and Capacitance
An electrostatic force is a force caused by stationary electric charges /fields. The electrostatic force is caused by the transfer of electrons in conducting materials. Coulomb’s law determines the amount of force between two stationary, charged particles. The electric force is the force which acts between two stationary charges. It is also called Coulomb force.
Responses should be as simple as possible, and in typed form, with all applicable units, following a clear and straightforward logical structure. NO hand-drawn explanations are allowed. Ensure the appropriate use of significant figures, and when applicable, employ the "variable space" framework for providing answers.
