The churning air in the troposphere helps determine the altitude of a place
The altimeter reading is 29.17 from the Kollsman window is 29.17 in Hg
<h3>How to determine the
altimeter reading?</h3>
The given parameters are:
- Ground level = 700 ft i.e. the field elevation
- Pressure altitude = 1450 ft
The pressure altitude is calculated as:
Altitude = (29.92 – Altimeter reading) * 1,000 + Ground level
Substitute the known values
1450 = (29.92 - Altimeter reading) * 1000 + 700
Subtract 700 from both sides
750 = (29.92 - Altimeter reading) * 1000
Divide through by 1000
0.75 = 29.92 - Altimeter reading
Evaluate the like terms
Altimeter reading = 29.17
Hence, the altimeter reading is 29.17 from the Kollsman window is 29.17 in Hg

Answer:
Normal Force is usually perpendicular to the movement and static friction usually means that there is no movement.
Explanation:
The work donde by any force on an object is equal to the displacement of the object multiplied by the component of the force that is in the direction of the displacement.
Normal force is usually perpendicular to the movement, so there is no component in the direction of the displacement. This is why it is zero in most circumstances.
<em>Static</em> friction on the other hand, usually means that there is no movement at all (it's static). It means that there is no displacement between the object and ground (in most cases). If there is no displacement, there is no work.

Answer:
They were produced by stars that lived and died before our solar system was born.
Explanation:
According to what it's understood today, all elements heavier than hydrogen (including helium and excluding some that were created in laboratories) are created through nuclear fusion in the core of stars.
They start fusing hydrogen into helium, then as the star grows older helium is fused into beryllium and so on for all the periodic table.
So as far as science understands it today it's a literal truth that we are made of stars. (as almost everything else)
