Answer:
it is diffuluct for a human because we understand so littlebout how to build a self-sustaining ecosystem that can support us, especially under tight constraints as to its total mass. Simply getting into Earth orbit
Explanation:
That is why it is diffulcut
Using the law of conservation of angular momentum, we have
<span>I1 w1 = I2 w2 </span>
<span>ie., m1r^2/2 x w1 = ( m1r^2/2 + m2r^2 ) w2 </span>
<span>ie., new angular velocity w2 = m1 w1 / ( m1+ 2m2) = 125 x 3.1 / ( 125 + 2 x39.5 ) </span>
<span>= 1.8995 = 1.9 rad /sec ( nearly )</span>
Indeed because some leave headlights off and ignore that fact since there are street lights around.
A white dwarf cannot support its own weight by its degenerate pressure if its mass is greater than 1.4 solar masses.
<h3>
What are white dwarfs?</h3>
White dwarfs are stellar core remnant composed mostly of electron-degenerate matter.
White dwarf is very dense due to its large mass and smaller volume.
<h3>Reasons for comparable mass of white dwarfs and Sun</h3>
- Stars with main sequence masses less than about 0.5 solar masses cannot ignite the helium fusion required to become white dwarfs.
- A white dwarf cannot support its own weight by its degenerate pressure if its mass is greater than 1.4 solar masses.
