Explain the meaning of the terms 鈥渞ed shift鈥� and 鈥渂lue shift鈥� as they relate to the relativistic Doppler effect.
(a) Using data from Table\(7.1\), find the mass destroyed when the energy in a barrel of crude oil is released.
(b) Given these barrels contain\(200\)litres and assuming the density of crude oil is\(750{\rm{ }}kg/{m^3}\), what is the ratio of mass destroyed to original mass,\(\Delta m/m\)?
Does motion affect the rate of a clock as measured by an observer moving with it? Does motion affect how an observer moving relative to a clock measures its rate?
Is the relativistic Doppler effect consistent with the classical Doppler effect in the respect that\({{\rm{\lambda }}_{{\rm{obs}}}}\)is larger for motion away?
(a) A nuclear power plant converts energy from nuclear fission into electricity with an efficiency of\(35.0\% \). How much mass is destroyed in one year to produce a continuous\(1000{\rm{ }}MW\)of electric power?
(b) Do you think it would be possible to observe this mass loss if the total mass of the fuel is\({10^4}{\rm{ }}kg\)?
