Example 2 Two waves traveling in opposite directions produce a standing
wave. The individual wave functions are
y, = 4 sin (3x - 2t)
y2 = 4 sin (3x + 2t)
where x and y are measured in centimeters and t is in seconds.
a. Find the amplitude of the simple harmonic motion of
the element of the medium located at r= 2.3 cm.
b. Find the positions of the nodes and antinodes if one
end of the string is at x = 0.
c. What is the maximum value of the position in the
simple harmonic motion of an element located at an
antinode?​

electromagnetic waves travel through space with vacuums. give me brainliest if right.

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.
