Explain why an object moving around a circle is said to be accelerating when it has no resultant force acting upon it.

If an object has no resultant force acting upon it then it is moving at a constant speed. Acceleration is a vector quantity meaning that it includes magnitude and direction. When it is moving around a circle...

Kinetic theory describes the movement of particles in three states of matter. If a cube of ice is put in a tin with a tight fitting lid and continuously heated, why does the lid explode off?

Before heating: Ice and air present in the tin, the ice particles vibrate about fixed positions, they do not exert a pressure on the lid at this time, air particles inside the tin hit the lid but exert the s...

State the principle of superposition of waves and illustrate it schematically.

Whenever two or more waves travelling through the same medium at the same time pass through each other, the net displacement of the medium at any point in space-time is simply given by the sum of the individ...

Whats the effective resistance in a parallel and series circuit with a cell and two 12 ohms resistors ?

What do we know about parallel circuits- Total current is equal to sum of the current in the individual branches I T = I 1 + I 2 Component of each branch of a circuit share the same voltage as the cell V 1 =...
