The neutron (n) is an unstable particle (decaying as n - pe ve) with an "average" lifetime of tn 882s, i. e., its abundance decreases as n(t)no exp(-t/tm) after initial production. suppose n's are produced on mars (for example, by a nuclear reactor) emitted in the direction of earth, 55 106 km away. (a) if the neutron is produced at a speed of 0.1c, how much time will pass in: (i) the earth-mars rest system (i) the neutron's rest system? (b) what percentage, p(t)-n(t)/no, of neutrons makes it to earth: (i) with; or (ii) without the effect of special realtivity? (c) repeat parts (a) and (b) for an initial speed of 0.5c.

An alpha particle with kinetic energy 12.5 mev makes a collision with lead nucleus, but it is not "aimed" at the center of the lead nucleus, and has an initial nonzero angular momentum (with respect to the stationary lead nucleus) of magnitude l = p0 b, where p0 is the magnitude of the initial momentum of the alpha particle and b=1.40×10−12 m. (assume that the lead nucleus remains stationary and that it may be treated as a point charge. the atomic number of lead is 82. the alpha particle is a helium nucleus, with atomic number 2.) what is the distance of closest approach?

Which sentences describe point source pollution? in this type of pollution, the source of the pollution is single and easily identifiable. when runoff water from the melting of snow mixes with debris, it creates pollution. the runoff water, mixed with pollutants, reaches large areas with disastrous effects. alternatively, when a wastewater treatment plant releases harmful chemicals into a stream, the chemicals pollute the stream water because they are not treated for safety.
