Using the initial information we can see that the acceleration in the 'y' direction is equal to 'g', so from this we can work out the velocity in the 'y' direction 'V(y)' by simply integrating the acce...

Ignoring the dark lines, we have a continuous colour (visible light) spectrum. The dark lines represent where the photon of a particular wavelength is missing, hence we cant see it. This occurs when th...

In a series circuit, the electrons passes through each component in order before returning to the cell. In a parallel circuit, there are different paths for the electrons to take so the current splits ...

Kinetic Energy (E_k) = 1/2(mv²).This can be rearranged such that, m = (2E_k)/v²we know from the question that E_k = 100 J and we know that v = 15 m/sso ...

Distance is a scalar, meaning it only has a magnitude. Displacement is a vector, meaning that it has both magnitude and direction. For instance, distance can state that I am "x" metres away f...
