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 ...

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...

To answer this question, we need to think about 3 things: interference, phase and path difference

In the experiment, we have monochromatic light (from a laser) going through two slits and then brig...

Firstly, I would start by drawing a diagram of the system on the whiteboard, showing the object attached to the string, and the string at a fixed point. I would show using arrows that the object was rotat...
