calculate the resistivity in a 1.2m length of cylindrical wire with radius 1cm. The resistance of the wire is 0.01 kilo Ohms

The primary equation in this calculation is rho = RA/L Where rho is resistivity, A is cross sectional area, L is length, and R is resistance

The resistance and length are given in the question. Res...

The LHC accelerates protons to a speed of 0.999999991c around a 27km ring. Due to relativistic effects, their mass increases. Given that the magnetic fields used are 8T, calculate this mass. What is the total energy of an LHC beam containing 3e14 protons?

Balancing the centripetal force mv^2/r with the force experienced due to motion in a magnetic field qvB: m = qBr/v = qBC/2piv (C circumference). Putting in numbers: m = 1.83e-23 kg (~11,000 mass of proton...

How does circular motion work?

Firstly, let's remember Newton's laws which tell us that in order for something to change direction of motion - like: going around in a circle - a net force needs to be acting on the object. In the case o...

Describe Newton's second law.

Newton's second law, F=ma, describes the relationship between an external force on an object F, the mass of the object m and the resulting acceleration of the object a. We can see that the acceleration of...
