2. a 75.0 kg astronaut is training for accelerations that he will experience upon reentry. he is placed in a centrifuge (r = 10.0 m) and spun at a constant angular velocity of 15.3 rpm. answer the following: a. what is the angular velocity of the centrifuge in rad/s? b. what is the linear velocity of the astronaut at the outer edge of the centrifuge? c. what is the centripetal acceleration of the astronaut at the end of the centrifuge? d. how many g’s does the astronaut experience? e. what is the centripetal force and net torque experienced by the astronaut? give magnitudes and directions.

answer; i believe the correct answer is (40,000 j) good luck

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.
