A rope has a density of 7.5 g/cm3 and a cross-sectional area of 2.0 cm2.
When the rope is subjected to a tension of 100 N, and one end is vibrated up and down with a frequency of 25 Hz, what is the (a) velocity of the transverse wave in the rope and (b) wavelength in Chapter the rope?
Explanation:
The density of a rope, d = 7.5 g/cm³
The cross-sectional area of the rope, A = 2 cm²
The tension in the rope, T = 100 N
One end is vibrated up and down with a frequency of 25 Hz.
(a) The velocity of the transverse wave in the rope is given by :
Mass per unit length will be :
[tex]\mu=\rho A\\\\=7.5\times 2\\\\=15\ cm[/tex]
So,
[tex]v=\sqrt{\dfrac{T}{\mu}}\\\\v=\sqrt{\dfrac{100}{15}}\\\\v=2.58\ m/s[/tex]
(b) Let [tex]\lambda[/tex] is the wavelength of the rope. So,
[tex]v=f\lambda\\\\\lambda=\dfrac{v}{f}\\\\\lambda=\dfrac{2.58}{25}\\\\\lambda=0.103\ m[/tex]
So, the velocity of the transverse wave in the rope is 2.58 m/s and the wavelength is 0.103 m.
(a) "2.58 m/s" would be the velocity.
(b) "0.103 m" would be the wavelength.
According to the question,
Density,
d = 7.5 g/cm³Cross-sectional area,
A = 2 cm²Tension,
T = 100 N(a)
Mass per unit:
→ [tex]\mu = \rho A[/tex]
[tex]= 7.5\times 2[/tex]
[tex]= 15 \ cm[/tex]
then,
The velocity of transverse wave will be:
→ [tex]v = \sqrt{\frac{T}{\mu} }[/tex]
[tex]= \sqrt{\frac{100}{15} }[/tex]
[tex]= 2.58 \ m/s[/tex]
(b)
The wavelength of rope will be:
→ [tex]v = f \lambda[/tex]
or,
→ [tex]\lambda = \frac{v}{f}[/tex]
[tex]= \frac{2.58}{25}[/tex]
[tex]= 0.103 \ m[/tex]
Thus the above answers are correct.

Explain the consequences that both positive and negative influences from peers can have on a teen's life.
Answer:
Look below!
Explanation:
Peers can make a huge influence on a teens life so who they surround themselves with is important. Some of the negative influences are lowering their self worth, pressuring them, or can lead them down a dangerous path. If teens surround themselves with the wrong people who cause a negative infuence on their lives, it could cause them to do things they wouldn't normally. However, the same could be said for a positive influence on a teens life but in a more positive light. A more positive influence from peers can help push the teen out of their comfort zone in a better way. They can encourage them and support their ideas and endavours which would lead to them becoming more self-confident.

c) organism-cells-tissues-organ systems-

d) tissues-cells-organs-organ sytems-

Answer:
Cells -> tissues -> organs -> organ systems -> organisms
The correct order of organization is cell-tissue-organs-organ systems-organism.
In biological organization, cells are the basic structural and functional units of life. Cells combine to form tissues, which are groups of similar cells working together to perform specific functions. Tissues then come together to form organs, which are structures made up of different types of tissues performing specialized functions. Organs further integrate and interact to create organ systems, which are groups of organs working together to carry out specific physiological functions. Lastly, all the organ systems combine to form a complete organism, such as a human or an animal. Therefore, the correct order is cell-tissue-organs-organ systems-organism.

Your appetite is learned and shaped by factors in your environment and by your emotions.
True or False?
True
False
True!
When some people have an environment that makes them upset it is actually very common for them to not want to eat whereas they are not feeling happy. Also I know this is true because the term (stress eating) rises from this, meaning that somebody could literally become hungry just because they are stressed out. It is sadly a very common problem too because it is bad for health and nutrition to just skip out on a meal, of which this same process confuses the bodily system, possibly even resulting in either more stress or even anger.

Explain how the respiratory system and the circulatory system work together to keep the body alive and well. Must be at least 3 sentences.
Answer:
The human respiratory and circulatory systems work together to supply the body with oxygen and get rid of waste carbon dioxide. While the former deals with air and the latter with blood, they work together seamlessly by coordinating the functions of the many parts of each system. Other systems in the body, such as the digestive system and the nervous system, are important too, but the circulatory and respiratory systems have to work continuously, usually without pausing even for a few minutes.
