Answer: F = ma,
Explanation:
the most famous equation in physics, establishing an equivalence between energy and mass. But is this the most important equation in physics? Knowledgeable scientists will tell you no. The most important equation in physics is F = ma, also known as Newton's second law of mechanics.
Answer:
The time required to penetrate the 40 cm clay layer is 126.82 years
Explanation:
Given:
Hydraulic gradient = 1 
Permeability of clay

Time required to penetrate 40 cm clay layer,


sec
But we have to find time in years,
years
years
Therefore, the time required to penetrate the 40 cm clay layer is 126.82 years
Answer:
gravitation
<em> good luck, hope this helps :)</em>
Answer: energy transfer. or, kinetic energy.
