Hard engineering is a method of coastal management that involves the building of large and generally expensive features in order to defend against the sea,this usually includes building sea walls, groynes...

A normal fault is a fault that involves extensional movement along its fault plane, this involves the hanging wall moving down in relation to the footwall. A reverse fault involves contraction along its f...

HCl + NaOH = NaCl + H2O. Moles = volume (dm3) x concentration (mol/dm3). Moles of NaOH: volume x concentration = (50/1000) x 0.3 = 0.015 moles. 1 to 1 ratio of HCl to NaOH, so there were 0.015 moles of HC...

Here it is necessary to use the chain rule to solve the derivative. If we equate our equation in terms of the following notation: ln(x)='u'and 2x^2='v' and use the chain rule formula dy/dx=udv/dx+vdu/dx w...

To solve this equation, we need to collect all of the x^2 terms and the x terms together. To do this we should start by getting rid of the fraction on the left-hand side by multiplying both sides by the d...
