A. write 2 -3 sentences describing the mass number, charge, and penetrating ability of gamma rays.

b. write the symbol for the nucleus that completes the nuclear equation:

c. write the symbol for the nucleus that completes the nuclear equation:

a. Mass number is the sum of number of protons and neutrons present in the nucleus of an atom.

A = p + n

Charge is a unit of matter that tells how more or less the number of electrons are present as compared to number of protons in an atom. A positive charge means the atom lacks electrons.

Gamma rays are highly energetic electromagnetic rays. They have high penetrating power and are very difficult to shield owing to high energy.

b. The compete nuclear equation is:

This is a alpha decay process because alpha particle which is Helium atom is being produced. Francium is being formed after alpha particle is emitted.

c. The complete nuclear reaction is:  

This is a positron emission process where in Rubidium is being formed.

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.
