1. the radius of a white dwarf is determined by a balance between the inward force of gravity and the outward push of .
2. a(n) occurs when hydrogen fusion ignites on the surface of a white dwarf in a binary system.
3. a(n) occurs when fusion creates iron in the core of a star.
4. a white dwarf in a close binary system will explode as a supernova if it gains enough mass to exceed the
5. a(n) consists of hot, swirling gas captured by a white dwarf (or neutron star or black hole) from a binary companion star.
6. a(n) can occur only in a binary system, and all such events are thought to have the same luminosity.

Mass (kg) force (n) 5 25 10 50 15 75 20 100 a student was trying to find the relationship between mass and force. he placed four different masses on a table and pulled them using a spring scale. the table shows the different masses used in the experiment and the force required to pull each mass. the student concluded that more force was required to pull heavier objects. what comment would you make regarding his conclusion? a) no clear relation can be observed between mass and force from the data. b) there is a direct proportion between the mass and force listed in the table. c) gravity should have been taken into account while performing the experiment. d) there is an inverse proportion between the mass and force listed in the table.
