Answer:

n=15 (No it's not cap)

Step-by-step explanation:

if the interior angle is 156 then to find the exterior angle we just do 180-156 which equals 24

360/24=15 so there are 15 sides

A beam of light from a monochromatic laser shines into a piece of glass. The glass has thickness L and index of refraction n=1.5

boyakko [2]

Additional information to complete the question:

How long does it take for a short pulse of light to travel from one end of the glass to the other?

Express your answer in terms of some or all of the variables f and L. Use the numeric value given for n in the introduction.

T = ___________ s

Answer:

$T = \frac{15}{f}$

Step-by-step explanation:

Given:

Thickness og glass = L

Index of refraction n=1.5

Frequency = f

$Wavelength = \frac{L}{10}$

λ(air) $= \frac{L}{10}$

λ(glass) = λ(air) / n

= $\frac{\frac{L}{10}}{1.5}$

= $\frac{L}{10} * \frac{1}{1.5}$

= $\frac{L}{15}$

V(glass) = fλ(glass)

$= f * \frac{L}{15}$

$T = \frac{L}{V_{glass}} = \frac{15}{f}$

Describe the solution of g(x) shown in the graph.

Ugo [173]

Answer:

All real solutions

Step-by-step explanation:

The given graph is a maximum quadratic function.
The solution to the graph is where the graph intersects the x-axis.
We can see from the graph that, the function intersected the x-axis at two different points, hence its discriminant is greater than zero.
Hence the solution of g(x) are two distinct real solutions.
The solutions are not whole numbers because the x-intercepts are not exact.
The solutions are also not all points that lie on g(x)
The first choice is correct.
