There are five major points on a typical metal's stress-strain graph. The first is the limit of proportionality. Prior to this point, the stress strain graph tends to be a straight line, ...

To understand why the drill produces more heat we must understand Lenz's law. Lenz's law states that the direction of an induced current is always such as to oppose the change that causes the current. In ...

Must include 3 points from 1-5 and 1 point from 6-7 for 4 marks.1.Strong nuclear force (SNF) affects nucleons or protons and neutrons.2. SNF attraction extends up to 3 fm (allow 1–4 fm) 3...

For capacitors in series (1/Total capacitance)=(1/capacitance1)+(1/capacitance2).1/C=[(1/(310^-6))+(1/(210^-6))]^-1Total capacitance=1.2*10^-6=1.2microfarad
