Two metal spheres, each of radius 4.0 cm, have a center-to-center separation of 4.00 m. sphere 1 has charge +2.30 10-8 c. sphere 2 has charge of -3.30 10-8c. assume that the separation is large enough for us to assume that the charge on each sphere is uniformly distributed (the spheres do not affect each other). take v = 0 at infinity.
(a) calculate the potential at the point halfway between the centers.
v
(b) calculate the potential on the surface of sphere 1.
v
(c) calculate the potential on the surface of sphere 2.

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.

  distance on the y-axis and time on the x-axis.

explanation:

the instantaneous velocity = change in position/time taken

the slope of the graph should give instantaneous velocity.

  slope of a graph = change in value of y -axis / change in values of x -axis

  comparing both the equations

    change in value of y -axis = change in position

  change in values of x -axis = time taken

so position values should be on the y axis and time values should be on the x axis.

distance on the y-axis and time on the x-axis.

that would be because of both gravity and friction. so     c
