This is the maximum velocity that an object can reach when falling through a medium (like air). Note that it occurs when the drag on the object equals the pull of gravity.

In order to find the unknown variables x and y we need to simplify these equations in the way that will make it possible for us to get rid of either x or y variable, and make it easier to solve the remaining...

At first glance, this may seem quite complicated. However, it is simple once you make use of exponents. Let y=ln(x) . This can be written as: e y = e ln(x) e to the power of a natural log cancels out, which ...

To differentiate this, we use the quotient rule as we have 2 functions of x as a fraction. The quotient rule states that: where u is the numerator function and v is the denominator function. Therefore, u=ln ...

Diffusion is the net passive movement of particles (atoms, ions or molecules) from a region in which they are in higher concentration to regions of lower concentration. It continues until the concentration o...
