Answer:

it travels at a different refractive index.

Explanation:

for example when light travels into water, it slows down, causing it to continue to travel at a different or another angle or direction. hope this helped!

Refraction of light occurs due to the different refractive indices of the medium in which the light travels.

<u>Explanation: </u>

The medium through which the light travels have different refractive indices, because of which the light rays crosses the boundary of the refractive indices. They are shifted from the travelling line according to the refractive index of the medium and hence, refraction is seen.

For example, air is medium with less refractive index as compared to glass, and therefore the light ray when enters into glass, travels slow and refracted from the actual path towards the normal of the ray.

What's the difference in a balanced force in an unbalanced force
AlekseyPX

There's no such thing as one balanced force or one unbalanced force.

If ALL of the forces in a GROUP of forces acting on the same object
all add up to zero, then we say that the GROUP of forces is balanced.

If they don't, then the GROUP of forces is unbalanced.

Two or more forces can be balanced or unbalanced.
One force can't.

Cold water will warm to room temperature faster in a: a) Black pot
Viktor [21]

Answer:

black pot

Explanation:

option a is correct

Cold water will warm to room temperature faster in a Black pot as we know that Black surfaces and good absorbers of heat in comparison to other surfaces. Moreover, Silver a good reflector of heat. It reflects most of heat incident on it, the cold water will take longer time to come the room temperature in Silver pot.

Find the equivalent resistance, the current supplied by the battery and the current through each resistor when the specified res
VLD [36.1K]

Answer:

R_{eq} = 19  Ω,   I = 0.105 A,   V1 = 1.05 V  and    V2 = 0.95 V

Explanation:

The correct way to solve this type of problem is to find the current or voltage values for the equivalent resistance and from here find the other values.

For a series circuit the equivalent resistance is the sum of the resistance

      R_{eq}= R1 + R2

       R_{eq} = 10 +9

       R_{eq} = 19  Ω

Let's use the equation for the voltage

     V = I R_{eq}

      I = V /  R_{eq}

      I = 2/19

      I = 0.105 A

In a series circuit the current is constant, so let's use the voltage equation for each resistor

     V1 = I R1

     V1 = 0.105 10

     V1 = 1.05 V

     V2 = 0.105 9

     V2 = 0.95 V

Note that the sum of this voltage is the total voltage applied.
