Answer:
The collision occurs at a height of 1/3 of the total height of cliff.
Explanation:
The situation is represented in the attached figure:
For the stone dropped from top of cliff we have
Initial velocity of drop= 0 m/s.
Now the time at which it attains a velocity of 2v is obtained from first equation of kinematics as
Thus the distance it covers in this time can be calculated using third equation of kinematics as
For the stone thrown upwards the velocity at collision is give as 'v' thus the velocity at which it is thrown upwards can be calculated by first equation of kinematics as
The height over which it changes it's velocity from '3v' to 'v' can be again obtained from third equation of kinematics as
Thus the collision occurs at at a fraction of 1/3 of height.
The overall verdict of the best method to use for teaching between asynchronous and synchronous teaching is:
- No clear winner, engage the students and make sure to answer any questions they might have.
<h3>What is Synchronous Teaching?</h3>
This refers to the type of learning where a person uses virtual means to learn, from a distance and attends class at a certain time.
An asynchronous teaching on the other hand is the type of learning where the student learn at their own pace and time.
With this in mind, there is no clear winner between the two as it is imperative to teach students in an engaging manner where they can ask questions, meet daily/weekly targets and understand concepts.

The process of ranking people based on factors such as weather, gender and ocuupation is known as "Social stratification".
<u>Explanation:</u>
Social stratification relates to a practice by which a community ranks classes of people in a hierarchy. The categorizing of people is based on socioeconomic constituents like wealth, income, occupation, gender, race, education and social status.
There are four principles in social stratification.
- A quality of society, not only a representation of individual differences.
- Social stratification leads to generation to generation.
- Social stratification is common but variable.
- Social stratification includes not just difference but faiths as well.
It is essential and unavoidable because of the necessity to influence people with the required knowledge and skills to choose to pursue careers that are most important to society.
Answer:
The Mental Status Exam (MSE) is the psychological equivalent of a physical exam that describes the mental state and behaviors of the person being seen. It includes both objective observations of the clinician and subjective descriptions given by the patient.
