Answer:
no
Explanation:
due to the refraction of light,meaning bending of light when it passes from diffrent mediums with diffrent densities
(probably mot the complete ans but smtg like this)
Answer:
b. Constant magnitude, but varying direction, perpendicular to the equipotential.
Explanation:
As we know that the relation between electric field and electric potential is given as

here if we say that potential is constant because electric field sensor is moving along equi-potential line.
Then we will say
V = constant
so we have

so electric field will remain constant always in magnitude and always remains perpendicular to the surface
so we have
b. Constant magnitude, but varying direction, perpendicular to the equipotential.
Answer:
The frequency of the coil is 7.07 Hz
Explanation:
Given;
number of turn of the coil, N = 200 turn
area of the coil, A = 300 cm² = 0.03 m²
magnitude of magnetic field, B = 30 mT = 0.03 T
maximum value of induced emf, E = 8 V
The maximum induced emf in the coil is given by;
E = NBAω
E = NBA(2πf)

where;
f is the frequency of the coil

Therefore, the frequency of the coil is 7.07 Hz
Answer:
Gravitational, Electrical, Magnetic, elastic potential, and chemical energy
Explanation:
When I did some research, I found 5 types of potential energy, so list the four that either came up in your lesson or are familiar to you:
Gravitational, Electrical, Magnetic, elastic potential, and/or chemical energy.
