The Frequency will be "266.14 Hz" and the number of loops are "60".
Explain the term harmonic motion?A simple periodic motion (such a pendulum swinging or a violin string making music) which has a specific frequency and amplitude or is made up of two or more of these motions.For the given question-
Tension T = 765 NLength L = 0.600 mMass m =4.50 gThe formula for the linear velocity is given as;
Linear density; μ = mass/length
Put the values,
μ = 4.5 x 10⁻³/0.6
μ = 7.5 x 10⁻³ kg/m
The formula for the fundamental frequency is;
F = (1/2L)√(T/ μ)
F = (1/2x0.6)√(765/ 7.5 x 10⁻³)
F = 266.14 hz
The number of loops is;
n = f'/f
n = 16000/266.14
n = 60
Thus, a person who can hear frequencies up to f = 16 kHz would be able to hear the highest harmonic with number n equal to 60.

The mean of a set of normally distributed data is 600 with a standard deviation of 20. What percent of the data is between 580 and 620?.
We know that 68.26% of data is between 580 and 620 using a normal distribution table.
What is a normal distribution?A data set must (when graphed) follow a bell-shaped, symmetrical curve that is centered around the mean in order to be regarded as having a normal distribution.
Additionally, it must follow the empirical rule that shows the proportion of the data set that lies within (plus or minus) 1, 2, and 3 standard deviations of the mean.
So, we know that:
μ = 600
σ = 20
Use the equation:
z - score = x-μ/σ
580 in the data's Z-score:
= 580-600/20
= -20/20
= -1
While the data's z-score in 620:
= 620-600/20
= 20/20
= 1
Using a table of the normal distribution:
P(580 < z) = 0.1587
Also, P(620 > z) = 0.8413
As a result, the percent of the data that falls between 580 and 620 is given by: P(620 > z) - P(580 z).
= 0.8413 - 0.1587
= 0.6826
= 68.26 %
Therefore, we know that 68.26% of the data is between 580 and 620 using a normal distribution table.

name the property if 3x= 4 and 4=z then 3 =z
The name of the property is transitive property if 3x= 4 and 4=z then 3 =z.
What is a transitive property?According to the transitive property, "if two quantities are equal to the third quantity, then we can claim that all quantities are equal to each other." The term transitive refers to the act of transferring something. If a, b, and c are three quantities and an is connected to b by some rule and b is related to c by the same rule, then a and c are related to each other by the same rule; this is known as the transitive property of equality.
The transitive property of equality states that if a = b and b = c for any values of a, b, and c, then a = c. In other words, because a and c are both equal to the same item (in this case, b), they must be equal as well.

Professional tennis players may constitute a(n) symbolic group for an amateur tennis player
A symbolic group is one in which a person is unlikely to be accepted even if they act like a member by emulating their beliefs, attitudes, and behaviors. For young people, cricket players like Sachin Tendulkar, Sourav Ganguly, etc., may serve as a representative group. By concentrating on the small scale, symbolic interactionism examines the individual within a community and their relationships with others.

(t/f) true or false. with sample size greater than 30, the standard error of sample means is the same as sample standard deviation.
The standard error for sample means is equal to the sample standard deviation when the sample size is more than 30 is a "false" statement.
Define the term standard error?When comparing a population mean to a sample mean, the standard error of mean, called simply standard error, shows how dissimilar the two are likely to be.It reveals how much doing the sample mean could change if a study were to be repeated with fresh samples drawn from a single population.For the stated question-
Let's assume that our sample size is 30 and that the population standard deviation is 10.
standard error = 10/√30 = 1.83
Now let me use a sample size of 100 while keeping overall population standard deviation constant.
=10/10 = 1
It is obvious that with this sample size, the standard error will alter.
Therefore, when our sample size grows, the standard error will drop rather than stay the same.
Thus, the standard error for sample means is equal to the sample standard deviation when the sample size is more than 30 is a "false" statement.

The domain is the set of all words in the English language that has a partial order relation and not a total order relation.
Given:
The domain is the set of all words in the English language (as defined by, say, Webster's dictionary.
Assume,
The domain is the set of all words in the English language (as defined by, say, Webster's dictionary). Word x is related to word y if x appears as a substring of y. x is a substring of y if all the letters in x appear in consecutive order somewhere in y. For example, "logical" is a substring of "topological" because the letters l-o-g-i-c-a-l appear consecutively in the order of the word "topological". However, "local" is not a substring of "topological" because the letters l-o are separated from c-a-l by the letters g and i.
Now, x is related to y if x is a substring of y.
Considering the following points through the example:
(A) Clearly, x is a substring of itself. Therefore, x is related to x and hence it is called reflexive.
(B) If x is related to y or y is related to x then x =y and it is called antisymmetric.
(C) If x is related to y and y is related to û then we can say that x is related to û (i.e. if x is a substring of y and y is a substring of û then x is also inscribed in û. Hence, we called it transitive.

What is simple interest?Simple interest is a quick and simple formula for figuring out how much interest will be charged on a loan. The daily interest rate, the principle, and the number of days between payments are multiplied to calculate simple interest.
Variable principal payments, or the portion of your mortgage payment that goes toward the loan itself rather than interest, are what give compound interest its feel.
Simple or compound interest are also possible. A loan's or deposit's initial principal serves as the foundation for simple interest.
Contrarily, compound interest is calculated based on both the principal amount and the interest that is accrued on it each period. Simple interest is simpler to calculate than compound interest because it is only applied to the principal.
According to our question-
In order to calculate compound interest, we would use the formula A = P(1+r/n)nt.
Where A = the account's total balance at the end of t years, and r is the interest rate.
The periodic interval at which it was compounded is represented by n.
P stands for the principal, or the initial deposit amount.
Since it was compounded once a year, A = 30000 r = 8% = 8/100 = 0.08 and n = 1 according to the information provided.
t = year
In light of this, 30000 = P(1 + 0.08/1)1 7 30000 = P(1.08)7 30000 = 1.7138P
P = 30000/1.7138 \s P = $17505
