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...

Read MoreBefore 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,...

Read MoreOne 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...

Read MoreThe ‘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...

Read MoreFrom 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...

Read MoreFaraday’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...

Read MoreA: 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...

Read MoreLet 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...

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