Tensile stress is formally defined as the force exerted on an elastic object per unit cross-sectional area.It has the same units as that of pressure, which are...

Before we dive into the derivation of Kepler’s Third Law from Newton’s Law of gravitation, we have to first understand what each of these laws means. First off,...

One can think of angular velocity as just the angular version of regular linear velocity: i.e. if linear velocity is defined as the rate of change of displaceme...

The ‘centre of gravity’ is a point through which the entire weight of an object seems to act through. I say ‘seem to’ because in reality, the object’s weight wo...

From the name itself, you can guess an important feature of the variable resistor: it’s resistance can vary. So with every new value of resistance, the amount o...

Faraday’s Law of electromagnetic induction states that the emf induced in a conductor is directly proportional to the rate of change of magnetic flux. Quantitat...

A: When it comes to solving numerical questions, it really helps to first write out the main equation, and see what quantities do we need:We can now see that we...

Let us first arrange our resistors R1 and R2 in parallel, and see what we getHere, we have to acknowledge that since R1 and R2 are sharing the same two junction...

Damping refers to the phenomenon where an object undergoing oscillations experiences resistive forces, such that it causes the amplitude of oscillations to decr...
