Observer B measures 6 seconds for this event. What time interval does A measure?

The mass of a particle called a muon as a function of its speed is shown in the graph below. ( mass / MeV / c 2 ) 1000 800 600 400 200 0 0.0 0.2 0.4 0.6 0.8 1.0 velocity / c Use the information in the graph to answer the following questions. (a) What is the rest mass of the muon? [1] ......................................................................... (b) At what speed would the muon need to be moving in order to have a mass of twice its rest mass? [2] ......................................................................... ......................................................................... ......................................................................... (c) If a constant force is applied to the muon, could this force ever accelerate it to a speed greater than the speed of light? Explain. ......................................................................... ......................................................................... ......................................................................... 881-181 [2] – 29 – N01/430/S(3) G3. One prediction of the General Theory of Relativity is gravitational redshift. Explain what is meant by the term gravitational redshift and outline an experiment that demonstrates the effect.
