Explanation:
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.

The muscle that alds in producing a movement but that is not primarily responsible for the movement is considered the
A. Synergist
B. Antagonist
C. Agonist
D. Prime mover
Answer: A. Synergist
Explanation:
The muscle that is primarily responsible for a movement is called the
prime mover, also known as the agonist. The muscle that produces a contraction to help in creating the movement but doesn't have the primary responsibility for it is considered the synergist muscle.
The antagonist muscles are those that resist the change in the prime mover and cause movement in the opposing direction.

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.

Weight management may be easier for a person who inherited genes that tend toward obesity true or false?
Answer:
1. True
2. False
Explanation:
1. It is TRUE that the Situation that triggers you to eat is called environmental cues. This is because the environmental cue is an indication particularly those relating to the subjective state of humans minds. Through research, the environmental cue has been found to triggers people that are not feeling hungry to eat. For example, opening up the freezer and seeing your favorite drink or food.

Kathy Mitchell wants to share something with you. She's
not proud of it, and it's not a behavior she hopes you'll
emulate. It's just the truth: As a teen, Kathy drank alcohol
while pregnant with her daughter, Karli. It was a perilous
if unwitting mistake that has defined both of their lives.
Karli is now 43 but is the developmental age of a first-
grader. In the home she shares with her mother and
stepfather, she collects dolls and purses, and pores over
Hello Kitty coloring and sticker books. Karli has fetal
alcohol syndrome, the result of alcohol exposure in utero.
In middle age, Karli has none of the awareness, self-
determination and independence that most of us take for
granted. She can't recognize social cues, is easily led and
manipulated, and can't predict dangerous behaviors. She
can only follow one rule at a time and doesn't understand
sequence. She can cross a street at a lighted crosswalk,
but if the light is out, she'll step in front of a car. She likes
to wear pretty clothes but she can't remember to brush
What can you infer are the possible effects of fetal
alcohol syndrome?
Children can develop learning and behavioral
problems.
Children are more likely to imitate their parents'
behavior.
Children will take their independence for granted.
Children can better predict dangerous behaviors
and follow complex directions.

Answer:
true
Explanation:
The "size of one's bones" and the "location of fat stores" in the body are both inherited traits.
The heritability of fat storage in the body is said to be 60%. For example, if a person's mom stored most of her fats in her thighs, then her children are most likely to have a similar storage area for fats. This is also said to be true for bone sizes. A part of it is due to genetics while other factors include a person's lifestyle and nutrition.
