Which of the following accurately describes how a magnetic motor works a
A set of electric coils are placed in a magnetic field. When a current passes through the wire, it creates a reaction that causes the atoms to being to shift into place
b
A set of electric coils are placed in a magnetic field. When a current passes through them, they create a magnetic field which interacts with the first magnetic field, causing the set of coils to rotate
c
A set of magnets are placed in an electric field. As the current increases or decreases, the strength of the electric field changes, causing the magnet to be more or less moved by the field
d
A set of magnets are placed in an electric field. A current is run through the magnets, thus increasing their magnetic fields. Once the magnetic field is increased, the magnets can be manipulated by the electric field by being guided around

i think it’s a. this is because if they measured the mass of something with a mass of 150g, then their final answer would have to be approximately 150g. though all of their answers are almost 150, rosa and tran have the closest answers (or the exact answer) to the accurate one.

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.

c)as speed changes, wavelength and frequency change.

everything changes!
