<u>Answer:</u>
Chile is similar to Venezuela in terms of arable land as the percentage of arable land in both the countries is below 4%.
Explanation:
- The economies of the South American countries of Chile and Venezuela are majorly dependent on fishing and allied businesses as agriculture in these two countries is close to impossible owing to the unavailability of arable land.
- The percentage of arable land in Chile is approximately 2% whereas the same for Venezuela is Approximately 3%. These negligible percentages of arable land leave the agricultural sector in the countries on the third spot after the services and industry sectors.
The answer is A, the first one
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.
