Answer:
the exposed core of a dead star, supported by electron degeneracy pressure.
Explanation:
A white dwarf is a low luminosity exposed core of a dead star having mass comparable to the sun but volume comparable to the earth . So its density is very high . These stars have lost the capacity to generate energy through the process of fusion . Due to high gravitational energy , it goes on shrinking but ultimately balanced by electron degeneracy pressure. It is not a main sequence star as it has lost the power of fusion .
Work is (force applied) x (distance through which the force moves).
Since the suitcase doesn't move up or down during the 15 minutes,
no work is done ... zero, zip, nada ... according to the real Physics
definition of 'work'.
So you problem ask to find or calculate the approximate diameter of the planet Neptune, based on my calculation the diameter of Planet Neptune would be 5972. I hope you are satisfied with my answer and feel free to ask form more.
Since the amount of matter does not effect average kinetic energy, it must have a higher average kinetic energy. (b)
Answer:0.10283 J
Explanation:
Given
mass of block(m)=0.0475 kg
radius of track (r)=0.425 m
when the Block is at Bottom Normal has a magnitude of 3.95 N
Force acting on block at bottom
u=5.583 m/s
At top point
v=3.188 m/s
Using Energy conservation
i.e. 0.10283 J of energy is wasted while moving up.
