The Young's modulus is a measure of the stiffness of the material - higher the young's modulus, higher the stiffness. It is calculated by dividing stress by strain over the elastic deformation region and ...

In order to tackle this question a general understanding of the the Kinetic Molecular Theory is required. The theory is based on assumptions of the behaviour of Ideal gases which are: Ideal gases are made...

To understand how an optical fibre transfers light, we must first understand the concept of 'total internal reflection'. Whenever light is refracted from one medium to another, the refractive index of the...

Original energy: GPE=509.81m KE=0 Final energy: GPE=0 KE=(1/2)mv² Therefore (1/2)mv² = 50m9.81 . The m cancels and simplifying the equation we are left with v^2...

For this question we would start by making f(x)=y. As we know the laws of logs, we can say that ln(x²)=2ln(x), therefore our equation can now be written as y= 2ln(x) - 4 . From this point, we w...
