i was getting £39500 last season before bonuses per weak, this season i wiil join Celtic fc in scottish and will earn £30000pw
E=zce^2/4pi r = mv^2 =nhv/w wherer w is the wavelength.zce^2/2w = nhv/w and v= zce^2/2nh = c Alpha/n where Alpha is the Fine Structure Constant 7.2e-3.V= 7.2e-3c/n = 2.16e6/n m/s. The speed of the electron is 2.16 mega m/s when n=1 the lowest level.
There is more to propellor geometry than just "size" (diameter). Props are also called out in pitch, which describes the forward distan a blade will travel in one rotation (ignoring losses) and is a function of both the foil (shape) of the blade and its angle relative to the line of thrust. If I am using a 14X14 prop, it may have less thrust that a 12X16, despite being 2 inches "bigger" because its blades are flatter and don't move as much air (or water) You can install the same outboard on two different boats and need a different pitch prop because of the differences in the two boats' displacements or hull shapes. The diameters are usually fixed on outboards so the pitch is adjusted...like differential ratios in cars.
