The index of refraction of silicate flint glass for red light is 1.620 and for violet light is 1.660. A beam of white light in t

his glass strikes the glass–air interface at a 22.50° angle of incidence and refracts out into air. What is the angular separation between the red and violet components of the spectrum that emerges from the glass?4

Answer:

0.33 degree

Explanation:

refractive index for red light = 1.62

refractive index for violet light = 1.66

angle of incidence, i = 22.5 degree

Use Snell's law for the red light

refractive index for red light = Sin i / Sin r

Where r be the angle of refraction for red light

1.62 = Sin 22.5 / Sin r

Sin r = 0.2362

r = 13.66 degree

Use Snell's law for the violet light

refractive index for violet light = Sin i / Sin r'

Where r' be the angle of refraction for violet light

1.66 = Sin 22.5 / Sin r'

Sin r' = 0.23053

r' = 13.33 degree

Angular separation between red and violet components = r - r'

                                                                  = 13.66 - 13.33 = 0.33 degree

Imagine Two Artificial Satellites Orbiting Earth At The Same Distance. One Satellite Has A Greater Mass Than The Other One? Whic
Bad White [126]

After reading this whole question, I feel like I've already
earned 5 points !

-- Two satellites at the same distance, different masses:

The forces of gravity between two objects are directly
proportional to the product of the objects' masses.  In
other words, the gravitational forces between the Earth
and an object on its surface are proportional to the mass of
the object.  In other words, people with more mass weigh more
on the Earth, and the Earth weighs more on them. 

If the satellites are both at the same distance from Earth,
then the Earth pulls on the one with more mass with greater
force, and also the one with more mass pulls on the Earth
with greater force.

-- Two satellites with the same mass, at different distances:

The forces of gravity between two objects are inversely
proportional to the square of the distance between them. 
In other words, the gravitational forces between the Earth
and an object are inversely proportional to the square of
the distance between the object and the center of the Earth. 

If the satellites both have the same mass, then the Earth
pulls on the nearer one with greater force, and also the
nearer one pulls on the Earth with greater force.

-- Resistor in a circuit when the voltage changes:

The resistance depends on how the resistor was manufactured. 
Its resistance is marked on it, and doesn't change.  It remains
the same whether the voltage changes, the current changes,
the time of day changes, the cost of oil changes, etc.

If you increase the voltage in the circuit where that resistor is
installed, the current through the resistor increases.  If the current
remains constant, then you can be sure that somebody snuck over
to your circuit when you weren't looking, and they either installed
another resistor in series with the original one to make the total
resistance bigger, or else they snipped the original one out of the
circuit and quickly connected one with more resistance in its place.

Choose the sentence that might be found in a personal narrative that correctly uses both a gerund and an infinitive.
Mumz [18]
Let's start with an infinitive: it has a form "to..." - only sentences C and D have a phrase like this, so we can exclude other options.

Among those, C does not have a gerund, which is a verbal form: "dreaming" has a function of a noun there.

So the correct answer is the remaining one, D.
