Answer:

D.) Diagram X shows refraction from a denser to a less dense medium, and diagram Y shows reflection.

Explanation:

As per ray diagram we can see that light ray moves from one medium to another medium

So this must be the phenomenon of refraction of light

Now in this phenomenon of light we can see that initially light makes small angle with the normal

After moving into the other medium the light makes more angle with the normal

so here light is bending away from the normal when it is moving into the other medium

So here light is moving into less denser medium from denser medium

So correct answer must be

D.) Diagram X shows refraction from a denser to a less dense medium, and diagram Y shows reflection.

The pressure exerted by a gas on its container is directly proportional to ________.
atroni [7]
<span>The pressure exerted by a gas on its container is directly proportional to the absolute temperature of the gas.

This result is known as "Gay-Lussac law", which states that for an ideal gas with fixed volume (like the gas in the container), the ratio between pressure and absolute temperature of the gas is constant:
</span>\frac{p}{T}=k
<span>where p is the pressure of the gas and T its absolute temperature.</span>

5. A helicopter scoops a load of water out of a lake, to dump on a forest fire. The helicopter exerts 6480
Strike441 [17]

Answer:

h = 250 m

Explanation:

Given that,

The helicopter exerts 6480  N of force on the water while rising high enough to fly over a mountain.

The helicopter does 1.62\times 10^6\ J of work on the water lifting it.

We need to find how high does it lift the water. Work done is given by :

W=Fh\\\\h=\dfrac{W}{F}\\\\h=\dfrac{1.62\times 10^6}{6480}\\\\h=250\ m

So, it can lift the water to a height of 250 m.

How many neutrons does an atom of Dubnium have in its nucleus
attashe74 [19]
Dubnium is a synthetic element ... Number 105.  It can be created
in a laboratory but it's not found in nature.

Fifteen (15) different isotopes of Dubnium have been created.  They all
have 105 protons in the nucleus of every atom, but they have anywhere
from 256 to 270 neutrons in each nucleus.

The most stable isotope of Dubnium is  ²⁶⁸Db , with 163 neutrons in the
nucleus.  That form of Dubnium atom has a 50-50 chance of surviving
for around 28 hours before it falls apart.
