the depth at which sounds travels slowest varies with latitude, from a few hundred meters deep in tropical and temperate latitudes to the surface around the poles.

Answers

Answer 1

In mid-latitudes, the sound moves slowest at a depth of about 1000 meters. Through the formation of a sound channel or waveguide (Deep sound channel), this minimum in sound speed allows sound to travel over great distances.

Temperature, salinity, and pressure all have an impact on the speed of sound in the ocean. With rising temperature, salinity, and pressure, sound propagates more quickly. At a depth of around 1000 m in mid-latitudes, the sound speed is at its lowest. As depth increases owing to a drop in temperature, sound speed near the surface drops. Because the sun warms the ocean's upper layers, the sound speed is high at the ocean's surface. The water temperature drops steadily with depth until it approaches a practically constant value of 2°C for depths below around 1000 m. As depth increases, the water temperature rises steadily. The water's pressure has the biggest impact on sound speed in regions where the temperature is nearly constant. As depth increases, pressure too does, causing an increase in sound speed. Compared to temperature or pressure, salinity has a much smaller impact on sound speed at most oceanic sites.

Bjorndal and Conrad wrote an article entitled "The dynamics of an open access fishery" in the Canadian Journal of Economics vol 20 issue1, pages 74-85. The article describes the dynamics of the North Sea herring fishery during the 1960s and 1970s. The fishery was in open access. The boats used are called "purse seiners" (their nets look like a big purse). Please refer to this article in answering the questions in Part 1. You do not need to read everything in the article to answer the questions below but you will find it helpful. You can download the article on the class webpage. 1. Set up an Excel spreadsheet to plot capital (K - the number of vessels) as a function of the size of herring stock (S) for the years 1963-1977 using Table 1. Entitle sheet 1 and your graph, "real data". Explain the biological dynamics and the vessel dynamics in detail. 2. If the production function is Cobb-Douglas, we have: Yt = aKt bSt g, we can write the dynamic system representing the fishery with the two difference equations: Kt+1=Kt+nπt/(ptKt) where πt = ptYt – ctKt St+1=St+rSt(1-St/L)-Yt. Let us assume the same parameters as in the text: a = 0.06157; b = 1.356; g = 0.562; L = 3,200,000; n = 0.1; r = 0.8 and the starting values S0 = 2,325,000 and K0=120. On sheet 2 of your excel spreadsheet, simulate stock size (S) , fleet size (K) and harvest (Y) using the dynamic system above for the years 1963-1977 along with cost per vessel and price of herring from Table 3. Plot capital as a function of the herring stock. Entitle the sheet 2 and your graph "simulated data".

Answers

To set up an Excel spreadsheet to plot capital (K) as a function of the size of herring stock (S) for the years 1963-1977 using Table 1, you can create two columns in Excel: one for the years (1963-1977) and one for the corresponding values of capital (K) based on Table 1. Then, you can plot a graph with the years on the x-axis and capital (K) on the y-axis. The title of the sheet and the graph should be "real data."

To create the Excel spreadsheet and plot the graph:

1. Open Excel and create a new spreadsheet.

2. In the first column, enter the years 1963-1977.

3. In the second column, enter the corresponding values of capital (K) based on the data from Table 1 in the Bjorndal and Conrad article.

4. Select the data in both columns.

5. Go to the "Insert" tab in the Excel ribbon and choose the type of graph you want to create (e.g., line graph, scatter plot).

6. Customize the graph by adding axis labels, a title, and any other desired formatting options.

7. Save the spreadsheet and the graph.

The biological dynamics of the fishery refer to the interactions between the size of the herring stock (S) and the harvest (Y). The vessel dynamics represent the changes in the fleet size (K) over time. By plotting capital (K) as a function of the herring stock (S), we can observe the relationship between these variables and analyze the dynamics of the fishery.

For the second part of the question, it involves simulating the stock size (S), fleet size (K), and harvest (Y) using the given dynamic system and parameters. This requires setting up difference equations and calculating the values iteratively based on the initial values and parameters.

By setting up an Excel spreadsheet and plotting the real data and simulated data, we can visually analyze the relationship between capital (K) and the size of the herring stock (S) in the North Sea fishery. This allows us to understand the biological and vessel dynamics of the fishery and explore the implications of different parameters and assumptions on the system's behavior.

scientists estimate that earth is about 4.6 billion years old. the fossil record shows the first chemical evidence of life around 3.8 nillion yeasr ago. what percentgage of earths history was without life? rwite a formula

Answers

Earth's age is about 4.6 billion years, according to scientists. Around 3.8 billion years ago, the fossil record reveals the first chemical evidence of life. %TwL = yE-yL/ yE *100

The following describes the variables:

%TwL denotes the proportion of Earth's history without life.

yE is the estimated age of the earth in years, and yL is the estimated time frame for the appearance of life.

The formula takes the earth's age minus the estimated time for life to appear, which is the amount of time the earth was without life, divides it by the earth's age, and finally multiplies the result by one hundred to get the percentage.

Which two pieces of evidence at the very least support the Earth's age of 4.6 billion years?

Geologists and astronomers alike agree that the Earth is approximately 4.6 billion years old. Using rubidium–strontium and uranium–lead dating, this age has been determined from the isotopic analysis of numerous meteorites, as well as soil and rock samples from the Moon.

How much of Earth's history was devoid of life?

Instead of 13.7 BY from the Big Bang, unicellular life appeared nearly 3.8 BY ago, making Earth's age nearly 4.6 BY. Nearly 82.6 percent is this percentage, which is 3.8 x 4.6 x 100.

explain how nearness to bodies of water, elevation, and location in relation to nearby landforms can influence climate

Answers

Nearness to bodies of water moderates temperatures and increases humidity. Higher elevation leads to cooler temperatures. Location in relation to landforms affects wind patterns and rainfall distribution. These factors collectively influence the climate of a region.

Nearness to bodies of water, elevation, and location in relation to nearby landforms are all significant factors that influence climate.

1. Nearness to Bodies of Water: Proximity to large bodies of water, such as oceans or lakes, can moderate temperatures and create a more maritime climate. Water has a higher heat capacity than land, meaning it takes longer to heat up or cool down. Coastal areas experience milder and more stable temperatures due to the moderating influence of the water. Additionally, bodies of water provide a source of moisture, leading to higher humidity levels and increased chances of precipitation.

2. Elevation: Higher elevations typically have cooler temperatures due to the decrease in air pressure and the associated adiabatic cooling effect. As air rises over mountains or highlands, it expands and cools, leading to the formation of clouds and precipitation. This results in cooler and often wetter conditions at higher elevations.

3. Location in Relation to Nearby Landforms: Landforms, such as mountains or hills, can act as barriers to prevailing winds and influence the distribution of precipitation. As air is forced to rise over these landforms, it cools and forms clouds, resulting in increased rainfall on the windward side. On the leeward side, however, the air descends and warms, leading to drier and sometimes desert-like conditions.

In summary, nearness to bodies of water can moderate temperatures and increase humidity, elevation affects temperature and precipitation patterns, and location in relation to landforms influences wind patterns and the distribution of rainfall. These factors work together to shape the climate of a particular region.

at apogee, the moon would appear___________from the earth and the tides would be ______________ .

Answers

The moon would appear smaller and the tides would be weaker from Earth at apogee.

At apogee, which is the farthest point in its elliptical orbit around the Earth, the moon would appear smaller from our planet compared to its appearance at perigee, the closest point in its orbit. This is due to the varying distance between the Earth and the moon as it moves in its elliptical path.

The moon's distance at apogee is approximately 405,500 kilometers (251,900 miles), which is about 30,000 kilometers (18,640 miles) farther away than its average distance from Earth. As a result, its apparent size in the sky is slightly smaller than usual.

In addition to the moon's size, the tides during apogee are also affected. Tides are primarily caused by the gravitational pull of the moon and the Sun on Earth's oceans. Since the moon's gravitational force is weaker at apogee due to the increased distance, the tidal bulges it creates are smaller. Consequently, the tidal range during apogee is reduced, resulting in weaker tides compared to those experienced during perigee.

Answers

The hand twists for the low- and high-pressure system models and the vertical motions of the palm of the hand are as follows:Low-Pressure System Model:For a low-pressure system model, the palm of the hand falls during the rotating motion of the hand.

The hand models used to represent atmospheric pressure systems in meteorology are based on the idea that warm air rises and cool air sinks. In the low-pressure system model, the palm of the hand is rotated in a counterclockwise direction, which indicates that warm air is rising at the center of the system.

In the high-pressure system model, the palm of the hand is rotated in a clockwise direction, which indicates that cool air is rising at the center of the system. These hand models are used to help visualize the movement of air masses and the formation of pressure systems. The direction of rotation of the hand is related to the direction of the pressure gradient, which is the change in air pressure with height. In a low-pressure system, the pressure gradient is from high pressure at the center to low pressure at the surface, and the hand rotates in a counterclockwise direction. In a high-pressure system, the pressure gradient is from low pressure at the center to high pressure at the surface, and the hand rotates in a clockwise direction.
