Answer:
Yes convection will always work faster and more efficiently.
Explanation:
When a gas or a liquid is heated, hot areas of the material flow and mix with the cool areas. ... Convection transfers heat over a distance faster than conduction. But ultimately conduction must transfer the heat from the gas to the other object, though molecular contact.
The momentul of the system preserves:
Ok, we found the speed after the collision.
Now, because the impact is plastic, it produces heat, sound energy and who knows what other forms of energy. We denote all this wasted energy with
.
Now, we write the energy conservation law:
From the above equation, you find
, and then conclude that the sound energy can certainly not be greater than this.
Particles that are closely packed but spaced apart enough to move over one another are called plasma. Option C is correct.
<h3>What is the plasma state of matter?</h3>
Plasma is a state of matter wherein particles are tightly packed but are far enough apart to slide over one another.
The following conditions are followed by the plasma state.
Hence, option C is correct.

It is fine to use the equation given by Plitter, since we are told that the mass is about the same as it is now, and I seriously doubt the original question wants the student to go into relativistic effects, electron degeneracy pressure and magnetic effects that govern a real white dwarf star.
There is no need to make it unnecessarily complicated, when the question is set at high school level. The question asks, given a particular radius, and a given mass, what will the density be (which in this case will be the average density). To answer the question, one needs to know the mass of the sun (which is about 2×1030 Kg. One needs to convert the diameter to a radius, and then calculate the spherical volume of the white dwarf. Then one can use the formula given above, namely density=mass/volume
