The average speed is the ratio between the total space and the total time of the motion:
The total space is
while the total time is
So, the average velocity is
We can also rewrite it in m/s. The total space is
, while the time is
, and so
Degeneracy pressure arises when sub-atomic particles are packed as tightly as the laws of quantum mechanics allow an object becomes as small as or smaller than Earth.
Answer: Option A
<u>Explanation:
</u>
Degeneracy pressure is the outcome of quantum degeneracy. As stated by Pauli’s exclusion principle, that two electrons of same quantum number cannot occupy the single shell, this leads to compression of shells.
So when the shells are getting compressed, the pressure will be created in the nucleus due to this compression which will be opposing the compression of space of the subatomic particles.
So the more the sub-atomic particles will be packed tightly, the more degenerate levels will be created leading to more compression of size of the atoms even smaller than Earth. This leads to increase in the degeneracy pressure as the interaction will increase between the nucleus and delocalized electrons on decreasing the size of atoms.

Answer:
0.80 m
Explanation:
Neglecting friction, the total mechanical energy of the pendulum is constant.
E = K + U where K = kinetic energy and U = potential energy.
At its release point of 0.80 m, the pendulum bob has a mechanical energy which is equal to its potential energy, since, its initial kinetic energy is zero. By the time the bob swings to the other end, it has a mechanical energy equal to it initial potential energy since total energy is conserved.
Neglecting friction, the pendulum bob would swing back to its original height of 0.80 m since the total mechanical energy is conserved and at its highest point, it is purely potential energy.
So, the height the pendulum bob swings to after release from a height of 0.80 m neglecting fiction is 0.80 m.
i dont know but i need the points soory may god bless you
