Aproton is projected with a velocity of 7.0 km/s into a magnetic field of 0.60 t perpendicular to the motion of the proton. what is the magnitude of the magnetic force that acts on the proton? (e = 1.60 × 10-19 c)

6.72 x 10⁻¹⁶ N

Explanation:

v = speed of the proton moving through the magnetic field = 7 km/s = 7000 m/s

B = magnitude of magnetic field in the region = 0.60 T

q = magnitude of charge on the proton = 1.6 x 10⁻¹⁹ C

θ = Angle of magnetic field with the velocity of proton = 90

F = magnitude of magnetic force

magnitude of magnetic force is given as

F = q v B Sinθ

F = (1.6 x 10⁻¹⁹) (7000) (0.60) Sin90

F = 6.72 x 10⁻¹⁶ N

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.
