Raley claims that Jordan ate it because he went to the bathroom first. Jordan claims that Raley ate it because she was trying to frame him. Who is lying?

The half life is 1000 years.

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

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.

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.

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

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

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.

Answer:  1. Factors taken into consideration while designing research questionnaires include the purpose of the research, target population, type of questions to be included, and the format of the questionnaire.

2. The principles of research questionnaires are reliability, validity, and objectivity. Reliability refers to the consistency and stability of the results, validity refers to the accuracy of the results, and objectivity refers to the absence of bias in the results.

3. Pros of questionnaires include the ability to reach a large number of people, the ability to gather standardized data, and the ability to analyze data easily. Cons include the potential for bias in responses, the difficulty in verifying responses, and the potential for low response rates.

4. Research design refers to the overall plan or strategy for conducting a study, including the type of data collection methods, sample size, and methods of analysis.

5.Types of sampling techniques used in research include random sampling, stratified sampling, and cluster sampling.

6. The rationales for the survey method in doing research activity include the ability to gather data from a large number of people, the ability to gather standardized data, and the ability to analyze data easily.

7. The importance of sampling is that it allows researchers to gather data from a representative sample of the population, rather than from the entire population. This saves time and resources and also helps to reduce bias in the results.

8. Characteristics of a good sample size include being representative of the population, being large enough to provide accurate results, and being drawn using a random sampling method.

9. Census in research method of data collection refers to collecting data from every member of the population. It is a comprehensive and detailed method of data collection, but it can also be time-consuming and expensive.
