A gate in an irrigation canal is constructed in the form of a trapezoid 4ft wide at the bottom, 8 ft wide at the top, and 2 ft high. It is placed vertically in the canal, with the water extending to its top. Find the hydrostatic force on one side of the gate.

Answers

Answer 1

The hydrostatic force on one side of the gate is 392 x 10³ N.

What is a hydrostatic force?

The force that results when a liquid under pressure acts on surfaces that are submerged is known as a hydrostatic force. Fundamental concepts in fluid mechanics include the calculation of the hydrostatic force and the location of the center of pressure.

Area of trapezoid =[(2 + 38) / 2 ] x 2 = 40 sq m .

Pressure at the centre of the trapezium

h d g = 1 x 10³ x 9.8 N / m²  ( height of centre is 1 m ) = 9800 N /m²

Total force required = pressure at the centre x total area

9800 x 40 = 392 x 10³ N.

Therefore, the hydrostatic force on one side of the gate is 392 x 10³ N.

Answer: Constructivism

Explanation:

After reading the information in chapter 8 and reviewing the videos on Ronald
Cotton Video 1 and Ronald Cotton Video 2, briefly describe the process (stages) of memory/remembering and then describe how interference, distortion, and distortion/error can alter memories, particularly the memory of an eyewitness to a crime or traumatic event. Do you believe eyewitness accounts of events are accurate enough to used in court cases? Why or why not?

Answers

The process of memory/remembering typically involves the following stages:

   Encoding: The process of taking in information through the senses and transforming it into a form that can be stored in memory.    Storage: The process of maintaining information in memory over time.    Retrieval: The process of accessing stored information and bringing it back into conscious awareness.

Interference, distortion, and error can alter memories in a number of ways. For example:

   Retroactive interference occurs when new information makes it difficult to recall previously learned information.    Proactive interference occurs when previously learned information interferes with the recall of new information.    The misinformation effect occurs when new information, often from misleading sources, changes or distorts previously held memories.

What is the memory about?

With regards to eyewitness accounts of events, research has shown that they can be inaccurate due to factors such as stress, the presence of weapons, and the amount of time elapsed between the event and the testimony. Eyewitness accounts can also be influenced by leading questions, the expectations of others, and the individual's own biases and beliefs.

Given these limitations, eyewitness accounts should be used with caution in court cases. While they can provide valuable information, they should be considered along with other forms of evidence and carefully evaluated for accuracy and reliability. Additionally, in some cases, expert testimony on the limitations and fallibilities of eyewitness accounts may be necessary in order to ensure that juries understand the potential limitations of eyewitness testimony.

Answers

Answer: Professors are "required to maintain a certain number of office hours per week to meet students," says Alice Lanning, who teaches a freshman-year experience class, also at Oklahoma. The problem is when "students don't take advantage of these office hours until the end of the semester and the grades get scary." Her advice? "Visit each professor at least once during the first month of school, ask what the professor covers and how to get the most out of the class." Lanning says. That's particularly critical because you'll have fewer exams and graded papers than in high school, so rebounding from a low grade is harder.

Professors are necessarily required to maintain a certain number of office hours per week to teach students, says Alice Lanning, who teaches a freshman-year experience class, also at Oklahoma.

What is the responsibility of a professor?

The responsibilities of a professor are deemed by the fact that they correspondingly work for universities as lecturers and researchers. A typical day for a professor includes teaching classes to graduate and undergraduate students.

They're expected to publish academic papers in peer-reviewed journals. They hold office hours to assist students who have difficulties with their courses.

One-eight of a radioactive isotope remains in an object after about 3,000 years. What is the half-life of that isotope?

Answers

The half life is 1000 years.

What is the half life?

Half-life is the time it takes for half of the radioactive atoms in a sample to decay. In other words, if you have a sample of a radioactive substance, after one half-life, half of the atoms will have decayed and half will remain. Each subsequent half-life will result in half of the remaining atoms decaying, until there are no longer any radioactive atoms left.

We know that we have the formula;

N/No = (1/2)^t/t1/2

N = Mass at time t

No = initial mass

t = time taken

t1/2 = half life

We have that;

1/8 = (1/2)^3000/t1/2

2^-3 = (2^-1)^3000/t1/2

2^-3 =2^-3000/t1/2

-3 = -3000/t1/2

t1/2 = 1000 years

(e) Assume there is another country called Macroville. If they use all of their resources they can either
produce a maximum or 20 boats or 30 cars. If both countries were to specialize in producing either
boats or cars, which good would each country produce? Explain.

Answers

Answer:

Out of all possible outcomes, it would most likely answer "d" as other options do not seem to match as well as answer D.

Explanation:

Below are the answers to some of these questions.

(a) The production possibilities curve for Microville represents increasing opportunity cost. This is because as more of one good is produced, the opportunity cost of producing another unit of that good increases. For example, if Microville produces more boats, the opportunity cost of producing another boat increases because they have to give up more cars to produce another boat.

(b) If Microville decided to produce 10 boats, their opportunity cost would be 10 cars. This is because for every boat they produce, they have to give up one car. Therefore, the opportunity cost of producing 10 boats is 10 cars.

(c) In order for Microville to be able to produce 15 boats and 15 cars, they would need to increase their production possibilities. This could be done through an increase in resources, such as labor or capital, or through technological advancements that increase productivity.

(d) Macroville has an absolute advantage in producing boats because they can produce a maximum of 20 boats while Microville can only produce a maximum of 15 boats. Absolute advantage is the ability to produce more of a good or service than another producer using the same amount of resources.

(e) If both countries were to specialize in producing either boats or cars, Microville should specialize in producing cars and Macroville should specialize in producing boats. This is because Microville has a comparative advantage in producing cars, as they can produce cars at a lower opportunity cost than Macroville. Similarly, Macroville has a comparative advantage in producing boats, as they can produce boats at a lower opportunity cost than Microville. By specializing in the good they have a comparative advantage in, both countries can produce more of that good and trade with each other to increase their overall production and consumption.
