A layer of ethyl alcohol (n = 1.361) is on top of water (n = 1.333). To the nearest degree, at what angle relative to the normal to the interface of the two liquids is light totally reflected?

From Snell's Law,

(ni)/(nr) = Sin (θr) / Sin (θi)

Where

θi = Angle of Incidence

θr = Angle of refraction

ni = Refractive index given for ethyl alcohol

nr = Refractive index of medium from which light is refracted

ni = 1.361

nr = 1.333

, θr = 90° ( Critical Angle is reffered to as Angle of Incidence at refracted angle of 90°) (θi = θc)

(ni)/(nr) = Sin (θr) / Sin (θi)

1.361/ 1.333 = Sin (90°)/ Sin( θc)

1.021= 0.894/ Sin( θc)

Sin( θc)= (0.9794

θc = Sin⁻¹ 0.9794)

θc = 78.35°

Explanation:

Each silicon atom has four valence electrons which are shared, forming covalent bonds with the four surrounding Si atoms.

Carbon contains four electrons in its outer shell. Therefore, it can form four covalent bonds with other atoms or molecules. The simplest organic carbon molecule is methane (CH4), in which four hydrogen atoms bind to a carbon atom (Figure 1).

The phenomenon of interference occurs when two wave pulses are traveling along a string toward each other. Option D is correct.

The result of two or more wave trains flowing in opposite directions on a crossing or coinciding pathways. This phenomenon is known as the interference of waves.

The effect is the sum of the individual wave amplitudes at each site where more than one wave is present.

When two wave pulses are traveling along a string toward each other. They meet and the phenomenon is occur known as interference.

Hence the phenomenon of interference occurs when two wave pulses are traveling along a string toward each other.

Answer:

C

Explanation:

frequency = 1 / period

so

frequency = 0.25

0.25 = 1 / period

1 / 0.25 = period

4 s = period

it is not 4 Hz because period is the time taken

so the answer is C

Answer:

m = 20 kg

Explanation:

Given that,

The speed of a body, v = 10 m/s

Kinetic energy of the body, K = 1000 J

We need to find the mass of the body. The formula for the kinetic energy of a body is given by :

[tex]K=\dfrac{1}{2}mv^2\\\\m=\dfrac{2K}{v^2}\\\\m=\dfrac{2\times 1000}{(10)^2}\\\\m=20\ kg[/tex]

So, the mass of the body is equal to 20 kg.

Answer:

Just as images are reflected from the surface of a mirror, light reflected from a smooth water surface also produced a clear image. ... Consequently, the outgoing rays are reflected at many different angles and the image is disrupted. Reflection from such a rough surface is called diffuse reflection and appears matte.

Answer:

Workdone = 1.96 Nm

Explanation:

Given the following data;

Mass = 100g to kg 100/1000 = 0.1Kg

Distance = 2m

To find the workdone;

First of all, we would determine the force acting on the apple

Force = mass * acceleration due to gravity

But, acceleration due to gravity is equal to 9.8m/s²

Force = 0.1 * 9.8

Force = 0.98N

Now, we can find the workdone using the formula;

Workdone = force* distance

Substituting into the equation, we have

Workdone = 0.98 * 2

Workdone = 1.96 Nm

Answer: The stratosphere and the troposphere are defined by the variation in temperature with height. Within a troposphere, the temperature drops as altitude increases, and drops fast enough for convection to occur. Whereas within a stratosphere, the temperature rises with increasing altitude. Features of the atmosphere change with altitude: density decreases, air pressure decreases, temperature changes vary. Different temperature gradients create different layers within the atmosphere. The lowest layer is the troposphere where most of the atmospheric gases and all of the planet's weather are located.

Answer:A:The track pushes back on Clinton's shoe with the same force.

Explanation:According to Newton's third law of motion, for every action force there is an equal and opposite reaction force. In this case, the action force is Clinton's shoe pushing on the track. As this happens, there is an equal and opposite reaction force in which the track pushes back on Clinton's shoe with the same force.

Answer:

There are two fundamental types of generators known as AC (alternating current) and DC (direct current) generators. While the technique of producing electricity is the same in both types, AC and DC power become different in terms of their applications – the way in which loads receive electric power.

Explanation:

An electric generator is a device that converts mechanical energy obtained from an external source into electrical energy as the output. ... Instead, it uses the mechanical energy supplied to it to force the movement of electric charges present in the wire of its windings through an external electric circuit.

The golf ball is two times as likely to be orange as it is to be pink. Therefore, option C is correct.

Probability can be described as the branch of mathematics of numerical descriptions of how likely an event is to take place. The probability of an event can be a number between 0 and 1, where 0 indicates the impossibility of the event and 1 shows certainty.

Given, the number of pink balls = 4

The number of white balls = 11

The number of orange balls = 8

The number of green balls = 18

The total number of balls = 4 + 11 + 8 + 18 = 41

When Felix picks a golf ball at random. The golf ball is more likely to be pink = 4/41

The probability golf ball is more likely to be white = 11/41

The probability  golf ball is more likely to be orange = 8/41

The probability golf ball is more likely to be green = 18/41

Therefore, the golf ball is two times as likely to be orange as it is to be pink.
