When placed in water does a pencil bend towards the normal or away from the normal?

ni sin theta i = nr sin theta r       where theta i is the angle of   incidence     and theta  r the angle of refraction

For nr greater than ni   (air to water) theta r must be smaller and the image would be bent towards the normal

probably not the "magnets"in the magnet, so to speak, are thought to be electrons orbiting in shells. vurrent loops two sides to the loop

distance = 150m

displ = root (50 ^2 + 100^2)

root(2500+10000)

root 125000
