Answer the following statement(s) true (T) or false (F)
1. A particle’s mass is the same in all inertial reference frames (even though its speed is not) 2. The components of a particle’s four-momentum are the same in all inertial reference frames. 3. As a particle’s speed approaches that of light, the difference between its relativistic momentum magnitude and its relativistic energy E becomes small (compared to E).

Fill in the blank(s) with correct word
Suppose a white dwarf is gaining mass because of accretion from a binary companion. What happens if its mass reaches the 1.4 solar mass limit?
A) The white dwarf undergoes a collapse and expels the excess mass in a nova eruption. B) The white dwarf (which is made mostly of carbon) suddenly detonates carbon fusion and this creates a white dwarf supernova explosion. C) A white dwarf can never gain enough mass to reach the limit because a strong stellar wind prevents the accreting material from reaching it in the first place. D) The white dwarf immediately collapses into a black hole, disappearing from view.
