Answer: The 4 ways human activities affect physical environment negatively is by driving vehicals and that causes Pollution and it harms the environment, persistent pollution problem (trash in the ocean) it harms the animals,oil pollution in the ocean and it harms and they can severely contaminate beaches and sediment, and cause serious harm to marine wildlife, the last thing is litter can also pollute the air.

The locating that IQ scores have increased dramatically during the last century is referred to as the Flynn impact.
The Flynn effect refers to a secular growth in population intelligence quotient (IQ) located at some point of the twentieth century (1–four). The modifications were rapid, with measured intelligence normally growing around three IQ factors per decade.
An instance of the Flynn effect is IQ rankings elevated by using 13.8 factors from 1932 to 1978. A similar price of growth was observed from 1972 to 2006.

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.
