Are vectors a1 and a2 perpendicular? If not, what is the angle between them? The angle is 120 degrees

Describe the procedure for adding a1 and a2 using vector resolution.

Vectors are added by placing them at the end of the second vector to the tip of the first one.

Which of the vector components shown has a negative value? Explain your answer.

Which of the two displacement vectors has a larger vertical component?

Which of the two displacement vectors has a larger horizontal component?

What equation would you use to calculate the components of a1?

What equation would you use to calculate the components of a2?

What equation would you use to add anet x and anet y?

What is the resultant of a1 and a2?

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.

luster is not a good characteristic to use by itself because luster is the property of minerals that indicates how much the surface of a mineral reflects light. the luster of a mineral is affected by the brilliance of the light used to observe the mineral surface.
