There are two ways to prove they intercept (you can choose whichever one you prefer). Say we have two straight lines, for example: r1 = 3i + 4...
6x + 2y = 2 and 12x -3y =18
Start by multiplying the first equation by two in order to balance both equations to have equal numbers of x
12x + 4y = 4 and 12x - 3y = 18
Rearrange both...
If we assume there is no air resistance, this means that the horizontal component of the ball's velocity won't change. Resolving horizontally we can see that the horizontal velocity = ucos(θ). We can ...
Here we have a product of two functions - they are being multiplied together - so we need to use the product rule. The product rule is: if y = u·v, dy/dx = v·u' + u·v' (where f' stands for df/dx). u = x^4...
Scientists have proposed several models of DNA replication but the currently accepted model is called the 'Semi-Conservative' model. The Semi-Conservative model of DNA replication was discovered by two sc...
