The main way in which an altimeter measures the altitude of an object is by calculating the location's air pressure.
<h3>What is an Altimeter?</h3>
This refers to the instrument that is used to measure the altitude of an object when it is at a fixed level.
Hence, we can see that an altimeter should NOT be confused with a barometer, because although they both measure pressure, a barometer calculates the change in air pressure and elevation based on available weather.
Please note that your question is incomplete so I gave you a general overview to help you get a better understanding of the concept.

Answer:
Explanation:
Let's start by calculating the angular velocity of the Moon. We know that the period is:
So now we can calculate its angular velocity:
The centripetal acceleration is given by
where
is the radius of the orbit
Substituting,
The density is 81.4 g/m3. Before you start plugging numbers into the density formula (D=M/V), you should convert 104 kg to grams, which ends up being 104,000 grams. Then you can plug in the 104,000 grams and 1,278 m3 into the formula. When you divide the mass by the volume, you get a really long decimal, which you can round to 81.4 g/m3, or whatever place your teacher wants you to round to.
Answer:
S-glass
Explanation:
The "S" in the S-glass signify strength and it a high tensile strength fiberglass that offer improved mechanical properties and lower density than the regular traditional glass (E-glass), thus it is an important component for building and aircraft structures.
