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.

Answer:
d. the echo faded before being stored in short-term memory.
Explanation:
The MOST plausible explanation for this phenomenon is that, in the latter case, <em>the echo faded before being stored in short-term memory</em>. Memory is the function that allows human beings to store experiences and to recall them when they are needed. Memory has three stages: sensory memory, short-term memory, and long-term memory. Sensory memory stores memories less than a second after the stimulus has stopped. In this experiment as the instructions came more than three seconds after the stimulus had stopped the students could not store it in short-term memory.

Answer: Collective conscience
Explanation:
Emile Durkheim believed that people in a society had certain norms, values, beliefs, morals and attitudes that they shared collectively and had an unspoken agreement to respect.
He called this the "Collective Conscience" and believed that it kept the society in question together. For instance, committing murder is shunned collectively by most if not all societies which makes it part of their collective conscience.
