What is the mass pf the planet (times the sine of the inclination of its orbit), mp sin i, in units of kg? (Note : you will need to use the answers to the previous two questions along with the relationship given next to the Doppler Wobble plot above.)

Which of the following correctly describes what happens when an atomic bomb explodes? small pieces of fissionable material are joined and form a body with a mass greater than the critical mass, the relative number of neutrons escaping decreases, and a chain reaction and explosion result. large pieces of fissionable matter are brought together quickly and form a body with a mass smaller than the critical mass, the relative number of escaping neutrons increases, and a chain reaction and explosion result.
