Chapter 37: Q. 9 (page 1081)

A 100-m-long train is heading for an 80-m-long tunnel. If the train moves sufficiently fast, is it possible, according to Experimenters on the ground, for the entire train to be inside the tunnel at one instant of time? Explain.

Short Answer

Expert verified

Yes.

Step by step solution

01

Step 1.  Explanation:

There are 2 event. Event 1 is the front of the train is at the entrance to the tunnel and event 2

is that the front of the train is at the tunnel exit. An experimenter on the ground will measure the

rear of the train to be at the tunnel entrance at the same time as event 2 due to length Contraction.

Firecrackers A and B are 600 m apart. You are standing exactly halfway between them. Your lab partner is 300 m on the other side of firecracker A. You see two flashes of light, from the two explosions, at exactly the same instant of time. Define event 1 to be 鈥渇irecracker A explodes鈥� and event 2 to be 鈥渇irecracker B explodes.鈥� According to your lab partner, based on measurements he or she makes, does event 1 occur before, after, or at the same time as event 2? Explain.

The Large Hadron Collider accelerates two beams of protons, which travel around the collider in opposite directions, to a total energy of 6.5TeVper proton. ( 1TeV=1teraelectron volt 1012eV) The beams cross at several points, and a few protons undergo headon collisions. Such collisions usually produce many subatomic particles, but in principle the colliding protons could produce a single subatomic particle at rest. (It would be unstable and would almost instantly decay into other subatomic particles.) What would be the mass, as a multiple of the proton's mass, of such a particle?

Consider the lead isotope 207Pb.
