#1. In an inertial frame S, astationary rod makes an angle θ with the x-axis. Another inertial frame S' moves with a velocity 'v' with respect ot S along the common x-x' axis. As obscrved from S' the angle made by the rod with the x'- axis is θ'. Which of the following statemcnts is correct ?

#2. A space crew has a life support system that can last only for 1000 hours. What minimum speed would be required for safe travel of the crew between two space stations separated by a fixed distance of 1.08 ×10^12 km ?

#3. Light takes 4 hours to cover the distance from Sun to Neptune. Ifyou travelin a spaceship at a speed 0.99c (where 'c' is the speed of light in vacuum), the time (in minutes) required to cover the same distance measured with a clock on the spaceship will be approximately

#4. A proton from outer space is moving towards earth with velocity 0.99c as measured in earth’s frame.A spaceship, traveling parallel to the proton, measures proton’s velocity to be 0.97c. The approximate velocity ofthe spaceship, in the earth’s frame is

#5. A collimated beam of pions originate from an accelerator and propagates in vacuum along a long straight beam pipe. The intensity of this beam was measured in the laboratory after a distance of 75 m and found to have dropped to one-fourth of its intensity at the point of origin. If the proper half-life of a pion is 1.77 x 10^-8s, the speed of the pions in the beam, as measured in the laboratory, must be

#6. In a certain intertial frame two light pulses are emitted at point 5 km apart and separated in time by 5 μs. At observer moving at a speed V along the line joining thesc points notes that the pulses are simultannus. Therefore V is

#7. A k meson (with a rest mass of 494 MeV) at rest decays into a muon (with a rest mass of 106 MeV) and; neutrino. The energy of the neutrino, which can be taken to be massless, is approximately

#8. In a certain inertial frame two light pulses are emitted, a distance 5 km apart and separated by 5 μs. At observer who is traveling. parallel to the line joining the points where the pulses are emitted, at a velocity V with respect to this frame notes that the pulses are simultancous. Therefore V is 

#9. Light takes approximately 8 minutes to travel fom the Sun to the Earth. Suppose in the frame ofthe Sun an event occurs at t = 0 at the Sun and another evet occurs on Earth at t =1 minute. The velocity ofthe inertial frame in which both these events are simultaneous is:

#10. The kinetic energy of a free relativistic particle is me ?, where E and m are its total energy and rest mass respectively. Let v, be the speed at which the kinetic energy equals the rest mass energy of the particle. Then

#11. A galaxy is receding relative to us at a speed of 3000 km/s. It emits hydrogen redline of wavelength 6560 Å. When seen by us, the wavelength of this radiation will appear to be

#12. Muons of kinetic energy E are produced in collision with a target in a laboratory. The mass of a muon is 106 MeV/c and its half-life is 1.4x10 s in its rest frame. What should be the minimum value of E if more than half the muons created at the target are to reach a detector 840 m away ?

#13. A muon, whose lifè-time at rest is 2 x 10^-6 sec, is travelling through the laboratory at three-fifh of the speed of light. It will last in

#14. Relative to a stationary observer, a rod of length 1.0 metre is moving at 0.8 times the speed of light in vacuum. It would appear to the observer that the rod’s length is :

#15. A particle is moving at a speed of 2.6 ×10^8 ms relative to the laboratory. Its lifetime as measured by an observer in the laboratory is 4.7 ×10^-6 s. The lifetime of the particle in its own rest frame is about
