A monopoly is where the market and one firm are coextensive.It has a downward sloping demand curve due to product differential. One key feature is that it has high barriers to entry. This means that it is ab...

Al has the higher first ionisation energy. Mg electronic configuration is [Ne]3s 2 whereas Al configuration is [Ne]3s 2 3p 1 . To remove the electron from Al, it has to be removed from the 3p orbital, as opp...

Ionisation energy is the energy required to remove one electron from an isolated gaseous atom (in its ground state). This generates a cation (ion with a positive charge). Both Mg and Al are in period three, ...

Getting a complicated problem of a mass being projected at a weird angle can seem daunting at first but these problems can be solved easily by breaking them down into two simpler problems.Using trigonometry,...

In this case the question has given you a clue as to the order that you solve the question. So, first we need to expand the brackets, multiplying each term by one another to get; y=8x^6 - 36x^4 + 6x^3 - 27x....
