Think about how each of noise, heat, visible light, radiation and atmospheric shock waves travel. Which ones require air particles to travel?

A vacuum has no air particles within it, it is completely empty.

Therefore, any of the above that requiring particles to travel will not be able to cross it and the observer will not experience it.

The sine of the incident angle is 0.217; the sine of the refracted angle is 0.173. Calculate the index of refraction.
Tju [1.3M]

Answer:

1.3.

Explanation:

From the question given above, the following data were obtained:

Sine of incident angle (Sine i) = 0.217

Sine of refracted angle (Sine r) = 0.173

Refractive index (n) =?

From snell's law, the Refractive index is simply defined as the ratio of the sine of the incident angle to sine of the refracted angle. Mathematically, it is expressed as:

Refractive index = Sine of incident angle / sine of refracted angle

n = Sine i / Sine r

With the above formula, we can obtain index of refraction as shown below:

Sine of incident angle (Sine i) = 0.217

Sine of refracted angle (Sine r) = 0.173

Refractive index (n) =?

n = Sine i / Sine r

n = 0.217 / 0.173

n = 1.3

Thus, the index of refraction is 1.3.

b) When the ball is near its maximum height it experiences a brief gust of wind that reduces its horizontal velocity by 2.50 m/s
fomenos

Answer:

The horizontal distance is 0.64 m.

Explanation:

Initial velocity, u =2.5m/s

The maximum horizontal distance is

R = \frac{u^2}{2g}\\\\R = \frac{2.5\times 2.5}{9.8}\\\\R = 0.64 m

Compare two processes we use to measure the age of Earth and its parts.
yan [13]

Answer:

Generally speaking, scientists have developed four different methods of determining the age of the earth. By using these methods, or a combination of them, the age of geological formations created by past events and even the fossilized bones of prehistoric animals can be determined.

Based on the research done by scientists, the Geologic Column, a graph that illustrates earth age, was developed. The Column, with its names for the epochs and eras of time, illustrates what scientists think was taking place in earth history. A small version of the Geologic Column is pictured at the right.

Explanation:

I hope this helps :)
