CERN Large Hadron Collider

Why is the Large Hadron Collider as large as it is?  I heard today that the actual accelerator portion is only 40 Meters long, the rest is (mostly) magnets that steer the particles, so why does the accelerator need to be 17 miles in circumference?  Does making it larger provide any advantages?

Sequence of Learning Physics

In what sequence should these chapters be prepared for my exams:-
units and dimensions,kinematics,laws of motion,work power and energy,motion of system of particles and rigid body dynamics,gravitation.

Answer:

It is better to follow the same pattern as given in NCERT text book

Can light do some mechanical work?

“We know that sound can cause some mechanical work(eg:when we keep our hand in front of a large speaker,we feel something hitting the back of our hand), but why this doesn’t happen with light??” -Manishankar asks.

Problem from Kinematics

The speed of a train changes from36km/h to 72km/h in 10sec. calculate the distance travelled during this time

Answer:

u=36km/h = 10 m/s

v=72 km/h=20 m/s

t=10 s

S=?

use v = u+ at to find a

a = 1 m/s2

Use v2-u2=2aS to find S

S = (400-100)/2 = 150 m

An idea shared by Eddie on speed of light barrier

If 24 lights in a series around a circle are wired so that each one switches on as soon as it “sees” the one next to it go on, and switches off as soon as it “sees” the one next to it go off, will the pattern of lights revolve around the circle at a speed close to the speed of light?
