Astudent moved up north along vector v1 and north east along vector v2 as shown in the diagram. if the magnitude of v1 is 7, x=4, and y=3 determine the magnutude of v2, the magnitude of r and the direction of r

x = 4

y = 3

From the diagram, it is clear that the x and y are the component of the vector. Since, x and y are perpendicular.

Hence,

Now, and x are in the same direction. Hence, we can add the magnitude.

= 7 + 4

y and are perpendicular and they are the components of R

Hence, the magnitude of R:

R = 11.4

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.
