Find the flux of earth's magnetic field of magnitude 5.00 3 1025 t through a square loop of area 20.0 cm2 (a) when the field is perpendicular to the plane of the loop, (b) when the field makes a 30.0° angle with the normal to the plane of the loop, and (c) when the field makes a 90.0° angle with the normal to the plane

Magnetic flux through a closed loop will be given by formula

here

B = magnetic field

A = area

= angle between normal to plane and magnetic field

Now we will use here the above formula for all the given conditions

i) magnetic field is normal to the plane

magnetic flux = BAcos0

ii) magnetic field makes 30 degree with normal to the plane

magnetic flux = BAcos30

iii) magnetic field is perpendicular to the normal of the plane

magnetic flux = BAcos90

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.
