A ray in benzene has a critical angle of 41.8 deg when trying to enter air. What is the index of refraction for benzene?

Physics
1 answer:
ziro4ka [17]3 years ago
3 0

Answer:

1.5

Explanation:

Data obtained from the question include:

C (critical angle) = 41.8°

n (refractive index od benzene) =?

Using the formula n = 1/sineC, the refractive index of benzene can be achieved as shown below:

n = 1/sineC

n = 1/sine 41.8°

n = 1.5

Therefore, the refractive index of benzene is 1.5

A cathedral hull allows a boat to do what?
nirvana33 [79]

Answer: A cathedral hull allows a boat to

(Get up on a plane quicker)

Explanation:

A boat is a device that is used for water transportation and other purposes. It is made up of various parts which includes:

- The HULL: this is the base( bottom) of a boat with the pointy forward part called the BOW and the flat back part called the STERN.

There are different types of hulls which can be constructed by boat manufacturers and it depends on the use of the boat. They include:

1.)displacement hull,

2.)planing hull,

3.) flat hull,

4.) round hull,

5.)v-shaped hull and

6.) multi-hulled boats.

Cathedral hull is a planing hull that allows a boat to get on a plane quicker. A boat is said to be "on a plane" when more power (and speed) is applied, lift increases, and the boat, in effect, rides over its bow wave, reducing wetted area and thus reducing drag. I hope this helps, thanks.

Which of the following solutions will have the lowest freezing point?
gregori [183]
 C. 1.0 mol/kg sodium phosphide (Na3P)<span> 

This is because it will produce 4 ions, and thus has the highest molalitiy. (more particles in solution lowers the freezing point) 

</span><span>remember if you ever need anything and you dont want to waste points you can just post it on my pfp or message me the question</span>

A rock has a mass of 3.1 kg. What is its weight on earth
Masteriza [31]

Answer:

W = 30.38 N

Explanation:

Given that,

Mass of a rock, m = 3.1 kg

We need to find the weight of the rock on the surface of Earth. Weight of an object is given by :

W = mg

g is the acceleration due to gravity, g = 9.8 m/s²

W = 3.1 kg × 9.8 m/s²

= 30.38 N

So, the weight of the rock on the Earth is 30.38 N.

A student discovers that sound waves travel 1,687.5 meters in 5 seconds through air at a temperature of 10°C. Based on this info
vitfil [10]

Answer:

The speed of sound, in m/s, through air at this temperature is 343.5 m/s

Explanation:

Given;

distance traveled by sound, d = 1,687.5 meters

time taken for the sound to travel, t = 5 seconds

air temperature, θ = 10°C

Speed of sound = distance traveled by sound / time taken for the sound to travel

Speed of sound = d / t

                           = 1687.5 m / 5 s

                           = 337.5 m/s

Speed of sound at the given temperature is calculated as;

c = 337.5 + 0.6θ

c = 337.5 + 0.6 x 10

c = 337.5 + 6

c = 343.5 m/s

Therefore, the speed of sound, in m/s, through air at this temperature is 343.5 m/s
