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.
Slaves were not because i hate to say it they were black and black people were slaves
Answer:
Exit Poll
Explanation:
Exit poll is the process of asking voter, who have given their vote and are leaving the polling booth, who they have casted their vote to. It is one of the method to collect information and try to extrapolate vote distribution pattern and based on that infer the winner of the election. This also helps to evaluate sentiment of voter for candidates.
Answer:b) based on determining long-term beneficial consequences
Explanation:In philosophy, egoism is the theory that is focused on self and what drives one's action.
Egoism has two variants, descriptive or normative. The descriptive (or positive) variant deals with human affairs. This variant describes that people are driven by perosnal interest and desires. The normative variant suggest that people are somehow motivated irrespective of what drives them. Ethical egoism is based on pursuing what is beneficial in one's life for a long term and what will be of benefits in their lives in a long run.
