What would cause a percent yield to be over 100? The percent yield is the ratio of the actual yield to the theoretical yield, expressed as a percentage. However, percent yields greater than 100% are possible if the measured product of the reaction contains impurities that cause its mass to be greater than it actually […]

What does atomic force microscopy measure? 3.7 Atomic-Force Microscopy AFM is used to measure and localize many forces, including adhesion strength, magnetic forces, and mechanical properties. AFM is performed using a sharp tip about 10–20 nm in diameter attached to a cantilever. Why is the atomic force microscope important to scientists? AFM is a very […]

How do you calculate power from voltage and resistance? Ohm’s law equation (formula): V = I × R and the power law equation (formula): P = I × V. P = power, I or J = Latin: influare, international ampere, or intensity and R = resistance. How do you calculate Ohm’s law? What is Ohm’s […]

What is group technology and cellular manufacturing? Group Technology exploits the similarity between component parts, by grouping them into part families that have similarities in their shape, and therefore require the same manufacturing operations. These are known as manufacturing “cells”, that can perform most or all of the operations required by a part family. In […]

What does passing on the right mean? Passing on the right is what you do when you’re on the highway, there’s someone in front of you who you want to pass, and you go around and pass them on their right rather than on their left as you normally would. Who must yield at roundabouts? […]

What is pn junction with diagram? Definition: A p-n junction is an interface or a boundary between two semiconductor material types, namely the p-type and the n-type, inside a semiconductor. The p-side or the positive side of the semiconductor has an excess of holes and the n-side or the negative side has an excess of […]
