The critical path is the path from the start to the end event continuously, with the end of one activity forming the start of the next. There is zero float and the project will be completed in the minimum...

Absorbed energy results in electron excitation. De-excitation then occurs, whereby electrons fall back down to the ground state. Energy levels are quantised, therefore each line represents a specific freq...

The photoelectric effect is one of the first pieces of experimental evidence of quantum mechanical phenomena. It describes how a material absorbs light and result in emission of electrons. Using a classic...

The chain rule is given by dy/dx= (dy/du)(du/dx). If we set u=6+2x+2x²then, y=u³ thus, dy/dx=(3u²)(2+4x) = (3(6+2x+2x²)²)(2+4x). Example does not ask...

During depolarisation, sodium ions move into the cell, resulting in the membrane potential rising from -70 millivolts (mV) to +40mV.During repolarisation, potassium ions move out of the cell, and the memb...
