Answer:

True

Explanation:

Short wavelengths, from high-pitched sounds, cause displacement of the basilar membrane near the oval window, is a True statement.

Stapes bones transmit movement to the oval windows. Stapes cause the round window membrane to move out. This turn allows the movement of fluid within the cochlea. This leads to motion of inner cochlear inner hair and thus hearing is possible.

Answer:

True

Explanation:

Before explaining the reason let's first know some of the terminologies used in the question.

Cochlea:

Cochlea is the spiral cavity of the inner ear which transform sound in neural message.

Basilar membrane:

The basilar membrane is a stiff structural element within the cochlea of the inner ear which separates two liquid-filled tubes running along the coil of cochlea.

Oval Window:

It is a membrane around the cochlea.

Volume of sound is directly proportional to the amplitude of a sound wave.

While the frequency of sound is inversely proportion to the wavelength of sound waves thus high pitch sound are produced by short wavelength and vice versa.

If the displacement of the basilar membrane is near to the oval window by a sound, then we can detect that sound, because sound waves stimulate the the basilar membrane and then sound waves are detected.

The structure of the cochlea varies, so sound waves of different wavelengths stimulate different areas in the basilar membrane.

shorter the wavelength higher is the chance to stimulate basilar membrane.

Increasing the pitch of sound (i.e. making the wavelength shorter) decreases the displacement of the basilar membrane to the oval window and thus we detect the sound waves.

If the vertical axis and time on the horizontal axis if the speed is steadily increasing could the speef line ever become perfec

Phantasy [73]

A graph of real speed can have a section that's as steep as you want,
but it can never be a perfectly vertical section.

Any vertical line on a graph, even it it's only a tiny tiny section, means
that at that moment in time, the speed had many different values.

It also means that the speed took no time to change from one value to
another, and THAT would mean infinite acceleration.

1. How do galaxies change over time? 2. How are galaxies created? 3. How was Hubble important to our understanding of galaxies?

VashaNatasha [74]

Hi!

1. Galaxies are constantly evolving with time, and one manner that they do this is that they change their rotation. This is apparent from the knowledge we have of initially formed galaxies which are spiral like in the beginning, but over time transform into what seems like smooth, barren disks. Another difference is that some galaxies are younger than others, and the age difference is observed with younger galaxies having a higher number of stars that are also comparatively brighter, which makes these galaxies look blue. Older galaxies contain older stars, and older stars are seen to give off red light, which is why these galaxies seem red. Galaxies also undergo various physical and chemical changes, and older galaxies are more structured.

2. Galaxies are brought into formation with the major factor being gravity. The force of gravity is responsible for attracting various stars, collapsing gas, dust clouds and other dark matter into a structured body. Over time the organization becomes more defined. So basically, a galaxy starts off as clouds of dust and stars in space, which come into proximity with other similar clouds, and their subsequent interactions shape the structure of the galaxy.

3. Edwin Hubble, also known as the 'pioneer of distant stars', has contributed to out understanding of galaxies in that he was the first person to prove the existence of galaxies other than the Milky Way, through his studies on spiral nebulae (which were formerly thought to be clouds of dust and gas, but were actually galaxies). He also established the relationship of red shift of a galaxy (recession velocity) and the distance of the galaxy from the Earth - a directly proportional relationship, which is known as the Hubble's Law.

4. The Milky Way is found to be considerably larger, about ten times, than the average dwarf galaxy being 100,000 light years across in diameter. The Milky Way is home to 200 billion stars, and with the capacity (dust and gas) to give rise to billions more. The Milky Way is the biggest galaxy in the Virgo Supercluster, and is relatively old in comparison with most other galaxies within the universe.

5. Dark matter and gravity play a role in determining the structure of the galaxy and influences the environment over time. Dark matter contributes to the mass of the galaxy, and this affects the spin of the galaxy. The more the mass of a galaxy (or more massive a galaxy) the greater would be its rotation. Gravity is the acting force that holds the components of galaxy in place, such as the dust clouds, colonies of star, gas and dark matter. Gravity influences the structure in that it exerts and inward pull on the stars, resulting in the spiral arm structure of a galaxy, which over time tends to be more eclipse like.

Hope this helps!

Atmospheric pressure decreases as altitude increases. in other words, there is more air pushing down on you at sea level, and th

Nutka1998 [239]

At sea level, the size amid the 2 alkanes lets for pentane to simmer at a lower temperature than hexane. Phenol has a higher boiling point due to hydrogen bonding High altitude would have the same order while low pressure only cuts the temperature at which a solvent boils. Boiling has to do with molecular size, the occurrence/nonappearance of hydrogen bonds, and other steric issues.
So the answer would be pentane high altitude, hexane high altitude, hexane sea level, hexanol sea level. In order of boil first to boil last. This is clarified because altitude has a better effect on vapor pressure (and hence boiling points) than inter-molecular forces.
