Which actions are ways to manipulate the magnet and wire loop in order to induce a current? check all that apply. move the magnet forward. move the loop away from the magnet. place the loop right next to the magnet, both stationary. move the loop sideways. move the magnet and loop in the same direction, at the same speed, at the same time. rotate the loop in place.

1, 2, 4, 6

Explanation:

Move the magnet forward.

Move the loop away from the magnet.

Move the loop sideways.

Rotate the loop in place.

speed of light in vacuum is 300,000 km/s

speed of light in other mediums is given by the expression v = c/n, where c is the speed of light in vacuum and n is the refractive index of medium.

for the first medium v = 200,000 km/s

  so, refractive index of medium = 300000/200000 = 1.5

    1.5 refractive index is usually for glass. so first medium is glass.

for the second medium v = 250,00 km/s

so, refractive index of medium = 300000/250000 = 1.2

    1.2 refractive index is usually for water. so second medium is water.

for the third medium v = 0 km/s

so, refractive index of medium = 300000/0 = ∞

    ∞ refractive index is usually for opaque mediums. so third medium is opaque medium.
