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

thermal energy is the answer

it's when something is going so fast it makes a loud noise, breaking the sound barrier, for example: a jet makes a loud noise, not only cause of the jet but because they reached a point where they went so fast that you can year the noise from various parts, kinda like a police car, lets say the car was going   so fast that you hear the siren of the cop car right next to you, but the car is probably a mile a way, it's cos the siren was next to you a few seconds if you understand me

can u provide the graph and if its not possible

then i can tell u the segment where the

average time interval starts degrading is the segment where the car is slowing down
