When a slab of insulating material is inserted between the plates of a charged capacitor, its capacitance a. is unaffected b. disappears c. increases d. decreases 3. All of the following affects the property to store energy of a parallel-plate capacitor; EXCEPT a. nature of the insulator between the plates b. thickness of the insulator between the plates c. distance between the plates d. the size of the conducting platesarrow_forward17 Silicon is a substance often used in electronic devices. Silicon has a high electrical resistance compared to metals which means that it does not release its electrons very easily. However, it does conduct electricity when the right conditions are met. These properties allow electronic devices to control the electrical current sent through silicon much easier than a typical metal substance. The properties of silicon would cause it to best be classified as a – A conductor B insulator C semiconductor D superconductorarrow_forwardThe number density of conduction electrons in a metal can be found from the density ρ of the metal, the mass per mole M of the metal, the number of conduction electrons per metal atom, and Avogadro’s number NA. If we assume one conduction electron per atom, which of the following gives the number density of conduction electrons for a given metal? a. NA ρM b.NA ρ/M c. NA M/ρ d. NA /ρMarrow_forward

Determine the characteristic energy of rotation in eV.arrow_forwardNote that in Figure 20.28, both the concentration gradient and the Coulomb force tend to move Na+ ions into the cell. What prevents this? Figure 20.28 The semipermeable membrane of a cell has different concentrations of ions inside and out. Diffusion moves the K+ and Cl ions in the direction shown, until the Coulomb force halts further transfer. This results in a layer of positive charge on the outside, a layer of negative charge on the inside, and thus a voltage across the cell membrane. The membrane is normally impermeable to Na+.arrow_forwardIf there is one free electron per atom of copper, what is the electron number density of this metal?arrow_forward
