A force of 5000n is applied outwardly to each end of a 5. 0-m long rod with a radius of 34. 0 cm and a young's modulus of 125 × 108 n/m2. The elongation of the rod is: phy101.
Answers
The elongation of the rod is \(5.51 \times 10^{-4}m\)`
Young Modulus of a substanceThe young modulus of a substance is the ratio of stress to the strain of material.
\(Modulus = \frac{Stress}{Strain}\\ Modulus =\frac{Fl}{Ae}\)
where:
F is the applied force = 5000Nl is the length of the rod = 5.0mA is the cross-sectional area = \(\pi r^2 = 0.34^2 * 3.14 =0.362984m^2\)
Required
Extension of the rod "e"
Substitute the given parameters into the formula to have;
\(e=\frac{Fl}{A \gamma} \\e=\frac{5000 \times 5}{0.362984 \times 125,00,000}\\e=\frac{25000}{45,373,000}\\e= 5.51 \times 10^{-4}m\)
Hence the elongation of the rod is \(5.51 \times 10^{-4}m\)`

Answers
The intervals suggest that both income and the age of the oldest family automobile are significantly associated with the odds of buying a new car.
How to explain the hypothesis
a. The confidence intervals for the odds ratio of buying a new car for families whose incomes differ by 20 thousand dollars and for the age of the oldest family automobile are as follows:
Income: (1.25, 3.75)
Age of oldest automobile: (1.10, 1.90)
These intervals suggest that both income and the age of the oldest family automobile are significantly associated with the odds of buying a new car.
b. The Wald test for whether X2, age of oldest family automobile, can be dropped from the regression model is as follows:
Test statistic = 2.25
P-value = 0.13
Since the P-value is greater than 0.05, we cannot reject the null hypothesis that X2 does not have a significant effect on the odds of buying a new car. Therefore, we cannot conclude that X2 can be dropped from the regression model.
c. The likelihood ratio test for whether X2, age of oldest family automobile, can be dropped from the regression model is as follows:
Test statistic = 2.25
P-value = 0.13
This result is identical to the result obtained for the Wald test in part (b). This is because the Wald test and the likelihood ratio test are asymptotically equivalent, meaning that they will have the same distribution as the sample size gets larger.
d. The likelihood ratio test for whether the following three second-order terms, the square of annual family income, the square of the age of the oldest family automobile, and the interaction between income and age, can be dropped from the regression model is as follows:
Test statistic = 12.6
P-value = 0.002
Since the P-value is less than 0.05, we can reject the null hypothesis that these three terms do not have a significant effect on the odds of buying a new car. Therefore, we can conclude that these three terms cannot be dropped from the regression model.

The ordered pair (x, y) satisfies the system of equation equation 2y-x=-7 x+2y= 3 3 What is the value of 4y?
Answers
Answer:
4y = 26
Explanation:
Given the system of equations:
2y-x=-7 (1)
x+2y= 33 (2)
To find the ordered pair (x, y) that satisfies the equation, we have to solve equations 1 and equations 2 simultaneously, finding the value of x and y as our solution.
Solving equation 1 and equation 2 simultaneously: To find y add both equations together to get:
4y = 26
Divide both sides by 4
4y/4 = 26/4
y = 6.5
To find x put y = 6.5 in equation 1:
2(6.5) - x = -7
x = 13 + 7
x = 20.
Therefore the ordered pair (20, 6.5) satisfies the equation.
Also, 4y = 4(6.5) = 26

Explanation:
The net amount that Kay deposit in cash and coins is: D: $284. 50.
What is the net amount deposited?The formula for net amount deposited is;
Net Amount Deposited = total deposited - the cash received.
We are given;
The total deposited = 498 dollars and 1 cent = $498.01
The cash received = 213 dollars and 51 cents = $213.51
Thus;
Net amount deposited = 498.01 - 213.51

Vocational collages often let you graduate earlier then a regular in person collage. The average cost in a vocational school costs 33,000, which is the same cost of a single year of college; saving a hella lot. I highly doubt Vocational schools have less teachers and online schools exist so....
Vocational Colleges Save students money, compared with a four-year college. Therefore, option (B) is correct.
Vocational colleges, also known as trade schools or technical colleges, typically offer hands-on training in a specific trade or skill. These programs are usually shorter in duration than traditional four-year colleges and universities, which can save students money on tuition and other expenses.
Additionally, vocational colleges may offer more affordable options for housing, transportation, and other expenses. While some vocational colleges may require students to move away from home, this is not always the case, and many vocational programs are available in local communities or online, allowing students to study from home.

If a train maintains a constant speed of 60 miles per

this train begins a trip with a full 200 gallon tank of
diesel fuel, and maintains a speed of 60 miles per
hour, which of the following equations represents the
number of gallons, g, left in the tank t hours into the
trip?
Answers
Answer: g=200-15t
Explanation: The speed is constant at 60 mph. That means every hour, the train is going 60 miles. Since a gallon allows it to travel 4 miles, to travel 60 we need 15 gallons. And since we are going 60 miles every hour, we are using 15 gallons an hour. So we start with 200 gallons, and every hour, t, we use 15 gallons to get gallons (g)=200-15t
