If a magnetic force does no work charged particles, how can it have any effect on the particles' motion?

answer:

magnetic force is always perpendicular to velocity, so that it does no work on the charged particle. the particle's kinetic energy and speed thus remain constant. the direction of motion is affected, but not the speed. this is typical of uniform circular motion.

hope it : )

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.

it has to be b, about 97 percent.
