Question
1. An experimenter determines a new particle created at one end of a laboratory apparatus moved at a speed of 0.9c and survived for 54 ns, decaying just as it reached the other end. a) According to the experimenter, how far did the particle move? b) According to the particle, how long did it survive? 2. An airplane is moving relative to the earth with a speed of 600 m/s. As determined by earth clocks, determine how long (in days) it will it take for the airplane's clock to fall behind by 2 us.... by utilizing the binomial approximation for the gamma factor: 3. A meter stick at an angle of 30° with respect to the positive x-axis in its reference frame. It is also moving horizontally with respect to an observer at a speed of 0.8c. Determine the length and angle of the meter stick according to the observer: 4. Red light emitted by hydrogen has a wavelength of a = 656 nm (as measured in a laboratory). An astronomer is studying a distant star (primarily composed of hydrogen) measures the wavelength of the hydrogen emitted light to be a = 736 nm. Determine the speed v of the star as it is moving away from earth (relative to the earth): 5 6 snareshin (mo = 6000 kg and L= 36 m) is observed to be 34.2 m while traveling away from the . 1 f11a/ino:Explanation / Answer
Solution :-
(1) distance = 0.94 x 3 x 108 x54 x 10-9 = 15.228 m
(2) T = To / sqrt (1 - V2 /c2)
T = 54/ sqrt (1 - 0.942)
T = 158.3113 us
