A ray of light traveling in water (n = 1.33) is incident at the flat surface of a block of glass (n = 1.60). If the incident ray

in water makes an angle of 36.6° with the normal to the interface, what angle does the ray that is refracted into the glass make with the normal?

Answer:

θ₂ ≈ 29.7°

Explanation:

Given:

n₁ = 1.33, n₂= 1.60, θ₁ = 36.6°, θ₂ = ?

Solution:

According to snell's Law

n₁ sin θ₁ = n₂ sin θ₂

1.33 × sin (36.6°) = 1.60 × sin θ₂

⇒ Sin θ₂ = 0.496

θ₂ ≈ 29.7°

Describe What It Was Like Before The Big Bang. Vision It In Your Head.
Inessa05 [86]
That's a loaded question. Well to me, through what I have heard from others and theories, I imagine there was other universes before us. It wasn't just nothingness, there was another universe, perhaps in another dimension that either ended or is still around today. Alternate dimensions are a theory, so it was probably just a matter of when ours would be born. We could've been the result of reaching the singularity in a black hole or we could've been the continuation of a grand generation of universes. Either way, I think before us there was other things that filled the void of darkness that we imagine to be before us.

The direction of an electric field is the direction (5 points) a negative test charge will move in the field a positive test cha
svet-max [94.6K]

Answer:

a positive test charge will move in the field

Explanation:

The direction of an electric field corresponds to the direction of motion of a positive test charge in the electric field. In fact:

- the electric field produced by a positive charge points outwards the charge --> this is because when a positive test charge is placed in this field, it will feel a repulsive force (because two positive charges repel each other), so it will move away from the positive charge that produces the field

- the electric field produced by a negative charge points towards the charge  itself--> this is because when a positive test charge is placed in this field, it will feel an attractive force (because a positive and a negative charge attract each other), so it will move toward the negative charge that produces the field.

iren [92.7K]

a person who alters their voice to make it seem as though the sound is coming from somewhere else, typically a puppet  is a ventriloquist.

<h3>Which ventriloquist was the best?</h3>

Jimmy Nelson, an American ventriloquist who performed on television in the 1950s and 1960s, was born on December 15, 1928.

<h3>What makes it a ventriloquist?</h3>

The incorrect but long-held notion that the voice came from the stomach is explained by the word ventriloquism's Latin roots, ventri (belly) and loquor (to talk).

<h3>Why is a ventriloquist good?</h3>

Making your puppet seem lifelike and honing your voice are essential for becoming a competent ventriloquist. To divert attention from yourself, keep moving the body, arms, and head of the creature. To assist people forget that your puppet is actually you, try to make the character as different from you as you can.

8. A tortoise moves a distance of 100 metres in 15 minutes. What is the average speed of
myrzilka [38]
Answer: 0.4 km/h



100 m = 0.1 km
15min./60min. = 0.25 hr

so, divide the total distance (100 m) by the total time (15 min)
0.1 km/0.25 hr = 0.4
