i need help solving this step by step with all the calculations Below is a set of absorbance data that you have obtained while doing an experiment studying the diffusion of potassium permanganate into solutions of water. This diffusion experiment was conducted at three temperatures. I need help to Calculate the diffusion rates for each of these temperature conditions.

(d) Calculate the electrical conductivity of a 6.0 mm diameter cylindrical silicon specimen of 60 mm long in which a current of 0.5 A passes in an axial direction. A voltage of 12.5 V is measured across two probes that are separated by 40 mm. i. Compute the electrical conductivity of the specimen. C12334 ii. Compute the resistance over the entire 60 mm of the specimen using the data in (1).
Why are resistors important in an electrical circuit? ) Resistors only allow a current to flow in one direction and can change alternating currents to direct currents. Resistors are electrical components that help to control the flow of the current in a circuit; they restrict the flow of electrons. ) Resistors consist of two pieces of conducting material separated by an insulating material called a dielectric. They are often used as timing devices, but they can transform electrical currents in other ways, too. ) Resistors can switch tiny electric currents on and off or amplify them.
