Reference frame S’ is to pass reference frame S at speed v along the common direction of the and x axes, as in Fig. 37-9. An observer who rides along with frame S’ is to count off a certain time interval on his wristwatch. The corresponding time interval ∆t is to be measured by an observer in frame S. Figure 37-22 gives ∆tversus speed parameter βfor a range of values for . The vertical axis scale is set by ta 14.0 s. What is interval ∆t if v = 0.98c?

Short Answer

Expert verified

The time interval for observer is 40s.

Step by step solution

01

Identification of given data

The speed of reference frame S’ is v=0.98c

The duration for the reference frame S’ is t=8s

The time dilation is used to find the duration for particle before decay from detector.

02

Determination of time interval for observer

The time interval for observer is given as:

∆t=t1-vc2

Here, cis the speed of light and its value is 3×108m/s.

Substitute all the values in equation.

∆t=8s1-0.98cc2∆t=40s

Therefore, the time interval for observer is 40 s .

If we intercept an electron having total energy of 1533 MeV that came from Vega, which is 26 ly from us, how far in light-years was the trip in the rest frame of the electron?


The premise of the Planet of the Apes movies and books is that hibernating astronauts travel far into Earth’s future, to a time when human civilization has been replaced by an ape civilization. Considering only special relativity, determine how far into Earth’s future the astronauts would travel if they slept for 120 y while traveling relative to Earth with a speed of 0.9990c, first outward from Earth and then back again?

In Fig. 37-26a, particle P is to move parallel to the x and x' axes of reference frames S and S' , at a certain velocity relative to frame S. Frame S'" width="9">x axis of frame S at velocity v. Figure 37-26b gives the velocity localid="1664359069513" u'of the particle relative to frame localid="1664359072841" S' for a range of values for v. The vertical axis scale is set by ua'=0.800c. What value willu' have if (a)v=0.90c and (b) v→c?
