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.
It's the imitation of others that ate observed and modeled
Answer:
true
Explanation:
British General Thomas Gage led a force of British soldiers from Boston to Lexington, where he planned to capture colonial radical leaders Sam Adams and John Hancock, and then head to Concord and seize their gunpowder. But American spies got wind of the plan, and with the help of riders such as Paul Revere, word spread to be ready for the British.
The answer is- the team leader is responsible for guiding a group of employees as they complete a project.
The definition of genetic determinism is that your choices and your destiny is already made or chosen for you by your genes and that you only have the illusion of free will, but that in reality it is known what will happen based on your biology. Many ideas like eugenics and IQ heredity are connected to this.
