The drawings show two examples in which a ray of light is refracted at the interface between two liquids. In each example the in

cident ray is in liquid
A and strikes the interface at the same angle of incidence. In one case the ray is refracted into liquid
B, and in the other it is refracted into liquid
C. The dashed lines denote the normals to the interfaces.
D.Rank the indices of refraction of the three liquids in descending order (largest first).

Answer:

Possible options:

A. nA, nC, nB

B. nA, nB, nC

C. nC, nB, nA

D. nC, nA, nB

E. nB, nA, nC

Answer is D

Explanation:

When the light is refracted into liquid B it is bent away from the normal, so that nA > nB. When the light is refracted into liquid C it is bent toward the normal, so that nC > nA. Therefore, we conclude that nC > nA > nB

What does a thermostat do if it gets too cool? ____________________________________ 2. what does a thermostat do if it gets too
Jet001 [13]
<span>If the thermostat gets too hot, it will turn off the heat an turn on the air conditioner. If a thermostat gets too cool it will turn on the heat or turn off the cold air. The human body is similar to a thermostat because if people get cold, they get covered in goosebumps, if they get too hot they begin to sweat.</span>

A coil formed by wrapping 65 turns of wire in the shape of a square is positioned in a magnetic field so that the normal to the
Fiesta28 [93]

Answer:

377 m

Explanation:

number of turns, N = 65

θ = 36°

B1 = 200 micro Tesla

B2 = 600 micro tesla

t = 0.4 s

induced emf, e = 80 mV

Let a be the side of the square coil.

e=\frac{d\phi }{dt}=NA\frac{dB}{dt}\times Sinθ

0.080=\frac{65\times a^{2}\times Sin36\times\left ( 600 - 200 \right )\times 10^{-6}}{0.4}

0.080=0.038a^{2}

a = 1.45 m

Total length of the wire, L = N x 4a = 65 x 4 x 1.45 = 377 m

Thus, the length of the wire is 377 m.

Bingel [31]

Answer:

A., B., and C.

Explanation:

An Ohmic material is a material that obeys Ohm's Law, V = IR.

In contrast, a non-Ohmic material is one that does not obey Ohm's law.

Ohm's law states that the voltage across an electrical object is proportional to the current flowing through it, with the constant of proportionality being Resistance, R (in Ohm's).

The only Non-Ohmic material is the semiconductor, as semiconductors do not obey Ohm's law.
