While on board a starship, you intercept signals from four shuttle craft that are moving either directly toward or directly away from you. The signals have the same proper frequency fo. The speed and direction (both relative to you) of the shuttle craft are (a) 0.3c toward, (b) 0.6c toward, (c) 0.3c away, and (d) 0.6c away. Rank the shuttle craft according to the frequency you receive, greatest first. Ob>a>c>d Oa>b>c>d Oa=b=c=d Od>c>a>b How much work must be done to increase the speed of an electron from (a) 0.16c to 0.20c and (b) from 0.94c to 0.98c? Note that the speed increase is 0.04c in both cases. (a) Number i Units (b) Number i Units In the reaction p +19 F -> + 160, the masses are: m(p) 1.007825 u, m(a) = 4.002603 u, = m(F) 18.998405 u, m(0) = 15.994915 u. = Calculate the Q of the reaction from these data.
