High above the stratosphere, the atmospheric temperature may reach 1091 k. however, spacecraft and astronauts do not burn up because the concentration of molecules is very low and molecular impacts on spaceships or astronauts transfer very little energy. what is the root-mean-square velocity, in m/s, of ozone molecules at that temperature

i need the answer to this too but idk 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.
