According to the Fermi gas model of the nucleus, its protons and neutrons exist in a box of nuclear dimensions and fill the lowest available quantum states to the extent permitted by the exclusion principle. Since both protons and neutrons have spins of 1/2 they are fermions and obey Fermi-Dirac statistics. (a) Find an equation for the Fermi energy in a nucleus under the assumption that A = 2Z. Note that the protons and neutrons must be considered separately. (b) What is the Fermi energy in such a nucleus for Ro = 1.2 fm? (c) In heavier nuclei, A > 2Z. What effect will this have on the Fermi energies for each type of particle?

sleep paralysis is a parasomnia, events associated with sleep.

sleep paralysis happens when you are in the middle of waking up or falling asleep. it is the feeling of being conscious but unable to move. it definitely involves hallucinations.

i had a friend that had sleep paralysis and he told me a story one time where he was laying in bed and he couldn't move his body no matter how hard he tried and there was someone standing in the corner of his room coming towards him. he couldn't move and you can't "wake up" because you are already conscious. sometimes sleep paralysis can be triggered by frequent waking up during the night based off of multiple trips to the bathroom, or if you had ever been abused, sleep paralysis can start happening from things like that.

explanation:

the masses of the objects and the distance between them

uranium fissions/breaks up giving out energy and neutrons

so easy. just google the electromagnetic waves and it’ll pop up.
