Identify the true statement. a. a particle of water in a wave moves in a circular motion when viewed in cross section. b. constructive interference of comparably sized swells tends to cancel them out and produce smooth water. c. wave base occurs at a depth equal to one-quarter of the prevailing wavelength in an area.

A.) A particle of water in a wave moves in a circular motion when viewed in cross section

Explanation:

Water waves are transverse waves. Waves transport energy, not water. As a wave crest passes, the water particles move in circular paths

The water particles don't move, they still end up in the place in which they began, the water particle moves up and down while the wave that passes through them moves in a perpendicular direction to the direction of the water particles moving up and down with respect to the crests and troughs of the wave (since water is a transverse wave). This will cause the wave to transverse in a circular path

The answer cannot be C because wavebase is equal to one-half the wavelength measured from still water level

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.
