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.

how do you assess if your community is healthy what are the characteristics of a healthy community
Answer: Health is the state of physical, mental, and social well being.
Explanation:
The assessment of the healthy society can be done by keeping in mind the parameters that are required to be checked upon the population like physical, mental and social health. The physical and mental health can be checked upon by routine check up like blood pressure check, weight, skin, assessment of any kind of chronic disease like chronic heart diseases, diabetes, obesity, and others. The less incidences of chronic and pandemic ailments can be considered in saying that the population is healthy. The community is said to be healthy when majority of the population is free from obesity, anemia, free from social disputes in the neighborhood, clean ambience, and pollution free surroundings.

Professor Devine and her colleagues are interested in assessing whether active versus passive play causes a preference for sweet or salty foods in toddlers. They assign groups of children to either an active play, passive play, or no play group and record their food choices when presented with a variety of sweet and salty foods. In this study, ________ is the independent variable and ________ is the control group.
Answer:
type of play, no play
Explanation:
In a study, the independent variable is the variable that isn't changed by the other variables during the experimental procedure. On the other hand, the dependent variable is the variable being tested/measured during the experiment (in this case, children's food choice), and therefore this variable is 'dependent' on the independent variable. Finally, the control group is the group where the independent variable is not manipulated, i.e., the group where participants do not receive the experimental treatment. A control group enables the establishment of causal-effects relationships by isolating the effects of the independent variable.

VariableA variable represents a measurable attribute that changes throughout an experiment, verifying the results. These attributes have different measures, depending on the variables, the context of the study or the limits that the researchers consider.
With this information, we can conclude that the active play and passive play group will be variables in Health, and the no play group will be the control group, because it will be in normal conditions.
