What is an anterior and posterior diameter ratio for the lungs with breathing?
The anterior-posterior diameter ratio of the lungs with breathing is typically 1:2. During inspiration, the chest expands leading to an increase in the anterior-posterior diameter of the lungs. This ratio can vary depending on factors like lung volume and individual anatomy.
What happens to velocity in adiabatic expansion?
In adiabatic expansion, the velocity of a gas increases because the gas expands into a lower pressure environment, converting internal energy into kinetic energy. This increase in velocity is a result of the conservation of energy and the need to maintain equilibrium as the system adjusts to the changing conditions.
When a low-mass star nears the end of its life it ejects shells of gas into space forming?
When a low-mass star nears the end of its life, it forms a planetary nebula by ejecting shells of gas into space. This is a result of the star shedding its outer layers as it transitions into a white dwarf. The ejected gas expands and glows, creating the beautiful nebula structures we observe in space.
Why are galaxies are a disk and not like a spherical object?
Galaxies are generally disk shapped, rather than spherical because of centrifugal force: Just like throwing a pizza crust in the air, it expands in the direction of its rotation. However, older galaxies (possibly the products of collisions of two or more galaxies) can result in blob-shapped galaxies that are more spherical.
Which is a star in its old age Protostar Main sequence Black Hole or Red giant?
A red giant is a star in its old age. During this stage, a star expands and cools as it exhausts its hydrogen fuel. Eventually, it will shed its outer layers, forming a planetary nebula.
What stars atmosphere expands a million times?
The star's atmosphere that expands a million times is called the planetary nebula. It is able to expand between 200 to 800 times the radius of the sun.
How spherical waves are produce?
Spherical waves are produced when a disturbance originates from a point source and propagates uniformly in all directions, creating a wavefront that expands spherically. This can occur in various natural phenomena such as sound waves spreading from a sound source or light waves radiating from a point light source. The energy in spherical waves diminishes as the wavefront expands, resulting in a decrease in intensity with increasing distance from the source.
Why Fluid Speed Increases in the Divergent Portion of a Convergent-Divergent nozzle?
Because the fluid is allowed to expand in the nozzle it increases velocity to fill in the voids created by the shape of the nozzle. The convergent point of the nozzle acts like a bottleneck trying to slow the fluid and compress it into the reduced crosssection of the nozzle. As it leaves the minimum crosssection it expands into the divergent spaces of the nozzle increasing in velocity as it expands. ++_+ No: it gains velocity through the convergence but in the diverging section, trades velocity for pressure.
What is an anterior and posterior diameter ratio for the lungs with breathing?
The anterior-posterior diameter ratio of the lungs with breathing is typically 1:2. During inspiration, the chest expands leading to an increase in the anterior-posterior diameter of the lungs. This ratio can vary depending on factors like lung volume and individual anatomy.

What is the shape of wavefront in light diverging from a point source?
The shape of a wavefront in light diverging from a point source is spherical. This means that the wavefront expands outward in all directions from the source, creating a series of concentric spheres.
Why frying pan does not expand on heating?
Every pan in general expands at least several nanometers in diameter when heated. Heat in general causes expansion of all materials.
Is a planetary neblua surrounded by planets?
The term "planetary nebula" is a bit misleading - it is a blob of glowing gas which expands from red giant stars late in their lives, thought to be pushed out from the outer layers of the stars by their stellar wind. There is a chance some planets may have been around at the time of the expansion, but that is by no means mandatory nor really indicative of the origin of the name.
How a star becames a white dwarf?
A white dwarf is the core of a dead star. As the star runs out of fuel, it expands into a red giant, as the shell of the red giant became a planetary nebula, and the core shrinks and became a white dwarf.
Why temp drops during throttling?
Throttling is the process of passing gas through a narrow opening at a high velocity. While doing so the gas expands thereby providing a cooling effect.
What size snake in a 3inch drain cleanout?
The cable is 3/4 to 1 inch diameter with a head that expands with the rotation. For a 3 inch drain you use a powered auger that turns the cable.
