To find the necessary power, we need to know how much water is flowing every second, and how much energy we need to heat that amount of water.
Amount of water = 6kg per minute = 6/60 kg per second = ...

First of all you must differentiate this function, as this will give you the gradient function necessary to find the gradient at the point (4,16). To differentiate it you use the formula dy/dx= a...

When attempting a source question, we must take a two-fold approach. The first step is to read it once or twice in order to gauge an overall tone and argument: ...

Balancing means that you have the same number of atom on one side as you do on the other. The reason for balancing is because atoms are not lost or created during a reaction. Keep in mind that when you ba...

The relationship between velocity, frequency and wavelength is given by: v=fλ.
In this case, we have: v=fλ₁ and v=2fλ₂ .Since the question states that the velocity is const...
