(i) At constant temperature, the pressure p and volume V of a gas are inversely proportional; pV = constant; ...

1. v=u+at Using a velocity time graph with constant acceleration, (graph provided as visual aid in tutorial) with initial velocity u and final velocity v, we can see that the graph is a straight line. ...

This is all down to how gravitational potential is defined. The gravitational potential at a point is defined as the work done per unit mass to move a mass from infinity to the point in the gravitational ...

Rutherford revolutionised the atomic model with this experiment. At that time, the general idea was that of JJ Thompson, the  "plum pudding" atomic model. Rutherford bombarded a sheet of gold wi...

The energy contained in a photon is given by the formula E = hf, where h is the Planck constant and f is the frequency of the photon. Since h = 4.110⁻¹⁵ eVs, f = E/h = 1.010^3<...
