Askater is standing still on a frictionless rink. herfriend
throws a frisbee straight at her. in which of the followingcases is
the largest momentum transferred to the skater?
a) the skater catches the frisbee and hols onto it.
b) the sjater catches the frisbee momentarily, but then
dropsit vertically downward.
c) the skater catches the frisbee, holds it momentarily,
andthrows it back to her friend.

option C

Explanation:

the correct answer is option C

Skater is standing on the frictionless surface when her friend through Frisbee at her he starts moving in the backward direction as there is no friction acting to stop him.  

but when again the skater through Frisbee back to his friend there is backward force which will increase the velocity of the skater.

so, momentum is directly proportional to velocity so, velocity increases momentum also increases.

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.
