So in the early experiments on cathode rays, Hertz (among others) attempted to detect deflection of a cathode ray passing through an electric field generated by two electric plates. However, his experiment had a fundamental flaw in producing the electric field. To gain the necessary magnitude in...

So this will definitely come up in Chemical Monitoring & Management, although you sort of get an introduction to it in Production of Materials. The correct method is as follows: 1. Name the halogens alphabetically 2. Number the halogens alphabetically as well (unless they are symmetrical, then...

Okay, so this was actually quite a tricky question, although definitely something that could come up in an exam. The all important line to watch out for is 28.7^k + 84k.7^k - 63k.7^k - 28 + 27, as this enables you to take out a common factor of 28 from 3 of the terms, substitute in and then take...

Okay, so the main problem with AC induction motors is that they require multi-phase electricity in order to produce the rotating magnetic field, which is really only available to commercial and industrial users. This means that household appliances such as a ceiling fan cannot use AC induction...

Could someone please PM me with some 2014 papers :) Thanks
