The number of protons in the nucleus dose not equal the number of neutrons.
<span>So the question is what is a transfer of heat within a liquid or gas that involves warm particles moving in currents. So there are three mechanisms of moving heat. Those are convection, conduction and radiation. Radiation is transfering energy via electromagnetic waves. Conduction is transfering heat trough some thermal conductor. Convection is transferring heat within a liquid or gas that involves warm particless moving in currents.</span>
To calculate the density of the white dwarf we need the mass of the Sun and the radius of the Earth:
- Sun mass:

- Earth radius:

Assuuming the dwarf to be a perfect sphere, its volume is

.
The average density is given by

so, substituting we find
work=force x displacement
so In order to do work, the force vector must be in the same direction as the displacement vector and the motion.
The answer is Galileo Galilei. Hope this helps :)
