B is the best answer to the question
Answer:
population and environment are integrated terms. They are interrelated in many respects. Health of an individual is directly associated with the environment in which one is living. Similarly, rapid population growth provokes massive environmental degradation.
Answer:
1.3
Explanation:
Relative density can be obtained from;
Upthrust in liquid/upthrust in water
Upthrust in liquid = Weight in air - Weight in liquid
upthrust in water = Weight in air - Weight in water
Hence;
Relative density = Weight in air - Weight in liquid/Weight in air - Weight in water
Relative density = 3.4 N - 1.5 N/ 3.4 N - 1.9 N
Relative density = 1.9 N/ 1.5 N
Relative density = 1.3
