52- Answer d
Explanation- Permeability is the ability to transmit water through interconnected pores,.
53- Answer- d
The change in 1 magnitude corresponds to approximately 30 times more energy. This is computed as mentioned below:
for change in magnitude from 5.5 to 6.5
the Change in shaking amplitude at 6.5 magnitude = 10 times the shaking amplitude of 5.5
Change in energy = (Change in shaking amplitude)^3/2
This roughly corresponds to a change of approximately 31.6 times energy
54- Answer b
