Electromagnetic radiation is emitted when a charged particle moves through a medium faster than the local speed of light. this radiation is known as cherenkov radiation. cherenkov radiation is found in many interesting places such as particle detectors and nuclear reactors and can even be seen by astronauts when cosmic rays traverse their eyes. it should be stressed that the particle is never going faster than the speed of light in vacuum (or c), just faster than the speed of light in the material (which is always less than c). the creation of cherenkov radiation occurs in much the same way that a sonic boom is created when a plane is moving faster than the speed of sound in the air. the various wavefronts that propagate in the material add coherently to create an effective shock wave. in this problem, you will become familiar with this type of radiation and learn how to use its properties to get information about the particles that created it?

a small object of mass 3.66 g and charge -17.6 µc is suspended motionless above the ground when immersed in a uniform electric field perpendicular to the ground. what are the magnitude and direction of the electric field?

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.
