Explanation: Working on it for homework right now and using my textbook

(a) The amplitude of the wave is 0.2 cm. The wavelength is 8 cm, the wave number is 0.125 rad/cm, the period is 0.04 s, and the velocity of the wave is 2 cm/s.

(b) The maximum transverse speed of any particle in the string is 5 cm/s.

(a) The equation of the transverse wave is given by y = 0.2 sin(π(0.125x - 25t)).

Amplitude (A): The amplitude of the wave is the maximum displacement of the particles from their equilibrium position. In this case, the amplitude is 0.2 cm.

Wavelength (λ): The wavelength is the distance between two consecutive points in the wave that are in phase. From the given equation, we can see that the coefficient of x inside the sine function is 0.125, which corresponds to 2π/0.125 = π/0.0625 = 8 cm. Therefore, the wavelength is 8 cm.

Wave Number (k): The wave number is the spatial frequency of the wave, defined as 2π divided by the wavelength. In this case, the wave number is 0.125 rad/cm.

Period (T): The period of the wave is the time taken for one complete cycle. In this case, the coefficient of t inside the sine function is 25, which corresponds to a period of 2π/25 ≈ 0.04 s.

Velocity (v): The velocity of the wave is the product of the wave number and the angular frequency. Since the angular frequency is given by 2π divided by the period, the velocity can be calculated as v = k/T = (0.125 rad/cm) / (0.04 s) = 2 cm/s.

(b) The maximum transverse speed of any particle in the string is equal to the maximum value of the derivative of the displacement function with respect to time.

Taking the derivative of y with respect to t, we get dy/dt = 0.2π(0.125x - 25)cos(π(0.125x - 25t)). The maximum value of the cosine function is 1, so the maximum transverse speed is given by |0.2π(0.125x - 25)| = 5 cm/s.

For energy to be transferred as heat between two bodies in physical contact, the bodies must be at different temperatures.

When two bodies are in physical contact, energy is transferred from the body at a higher temperature to the body at a lower temperature. This transfer of energy occurs through the mechanism of heat, which is the flow of thermal energy due to a temperature difference.

The rate of heat transfer depends on the temperature difference between the two bodies and the thermal conductivity of the materials they are made of. Heat always flows from hotter to colder regions until thermal equilibrium is reached, where both bodies reach the same temperature and there is no further net transfer of heat energy.

1. Ruth first gained fame as a pitcher.

Although best remembered for swatting a prodigious 714 home runs and slugging .690, which remains a major-league record, Ruth was one of baseball’s most dominant left-handed pitchers in the 1910s. He won 89 games in six seasons with the Boston Red Sox, including 24 in 1917, and helped the team win three World Series titles. Ruth only pitched five games for the New York Yankees as his position switched to outfielder after being sold by Boston before the 1920 season.

2. He did not retire as a New York Yankee.

Ruth’s major-league career not only started in Boston, it ended there as well, but not with the Red Sox. Discarded by the Yankees as his performance waned, Ruth signed with the National League’s Boston Braves in 1935 in the hopes of becoming the team’s manager the following season. When it became clear that his skills had deteriorated and the promise would not be kept, Ruth ended his 22-year career after just 28 games in a Braves uniform.

3. Ruth was not a unanimous choice for the Baseball Hall of Fame.

A year after his retirement, Ruth was among the five initial inductees elected to the new National Baseball Hall of Fame under construction in Cooperstown, New York. In spite of Ruth’s amazing career statistics, 11 of the 226 voters left him off their ballots, and the “Sultan of Swat” trailed Ty Cobb as the leading vote-getter. Ruth’s plaque in Cooperstown refers to him as baseball’s “greatest drawing card,” and proving the point, the Hall of Fame last month opened a new exhibit on Ruth to coincide with the centennial of his first big-league season.

Explanation:

The equilibrium temperature when equal masses of the first and third liquids are mixed is 22.8◦C.

To solve this problem, we need to use the principle of heat transfer and the fact that the total amount of heat in the system is conserved.
When equal masses of the first two liquids are mixed, the total heat in the system is the sum of the heat of the first liquid and the heat of the second liquid. Let's assume the specific heat capacity of the liquids is the same and equal to C. Then, we can write:
(m1 + m2)C(16 - (m1-m2)/2) = m1C(13 - (m1-m2)/2) + m2C(19 - (m1-m2)/2)
where m1 and m2 are the masses of the first two liquids. Solving for m1-m2, we get:
m1 - m2 = 12
Using the same approach, we can find that when equal masses of the second and third liquids are mixed, we have:
m2 - m3 = 10
Now, to find the equilibrium temperature when equal masses of the first and third liquids are mixed, we can use the same equation as before, but with m1 = m3:
2m1C(T - 16) = m1C(13 - 3m1/2) + m3C(33 - 3m1/2)
Simplifying and solving for T, we get:
T = 22.8◦C
Therefore, the equilibrium temperature when equal masses of the first and third liquids are mixed is 22.8◦C.

To find the value of ro, the inner radius of the spiral track on the CD, we need to use the given information and equations provided.

Let's convert this to millimeters, as the units of ro are in millimeters:

1.55 μm = 1.55 × 10^(-3) mm

To calculate the angular acceleration, we'll differentiate the equation of the spiral with respect to time:

dr/dθ = d(ro + 30)/dθ

=> 0 = d(ro)/dθ

Since the angular speed (dθ/dt) is constant, the derivative of ro with respect to time (d(ro)/dt) must be zero.

Given that ro is the inner radius of the track, we can express ro in terms of θ and then differentiate with respect to time:

The slope of the graph of the equation at the point (20, 2) is 1/8.

To find the slope of the graph of the equation at the given point (20, 2), we need to find the derivative of the equation with respect to x and evaluate it at x = 20. Let's differentiate the equation implicitly:

xy - 9y^2 = 4

To differentiate implicitly, we treat y as a function of x and apply the chain rule. Differentiating both sides of the equation with respect to x:

1 * y + x * dy/dx - 9 * 2y * dy/dx = 0

Simplifying this equation:

y + x * dy/dx - 18y * dy/dx = 0

Grouping the terms with dy/dx:

dy/dx * (x - 18y) = -y

Now, let's solve for dy/dx by dividing both sides by (x - 18y):

dy/dx = -y / (x - 18y)

Substituting the given point (20, 2) into the equation:

dy/dx = -2 / (20 - 18(2))
