Nitrogen has atomic number 7; so, when neutral, it has 7 electrons . Those electrons are organized according to the Aufbau principle in an electronic configuration of 1s² 2s² 2p^...

To start off with as it is two's compliment (from the first bit being 1) we have to flip all the bits to get 01101001, then we must add 1 to get 01101010. Then we simply convert this to decimal using norm...

The formula to be used here is C = Q / V. Where C = capacitance, Q = charge and V = potential difference. First we can put in the values to get 25 * 10^-6 = Q / 500. This can be rearranged to Q = 500 * 25...

Answer is 2x - 4. This is found by following the standard differentiation procedure of n(ax-b)^n-1 where n was the previous power and a and b are the value inside the bracket. This means that it first goe...

A number of river characteristics change as you travel downstream. Firstly, sediment size decreases due to erosion, which causes sediment to get finer and smoother. This happens due to hydraulic action, a...
