As the object is released two forces act on it.Its weight and and air resistance. At this point its weight is much greater due to the force of gravity on the object so it accelerates downward. As its s...

This question can be solved using suvat equations, since the acceleration due to gravity is constant. First make a list of the variables given in the question;

s=0.5m

u=0ms<...

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 ...
