Answer:
t√2.
Explanation:
Given that both are rest at initial position.
The time taken by stone A is t
h= 1/2 g t² ----------1
Lets time taken by stone B is t'
2 h= 1/2 g t'² -----------2
From equation 1 and 2
2 h= 1/2 g t'²
2 x 1/2 g t² = 1/2 g t'²
t'²=2 t²
t' = t√2
So the answer is t√2.
e. sqrt(2) .t
The answer from the given options is "A. Creep".
Alternate freezing and thawing often leads to "creep".
Creep refers to the low mass development of soil and soil material down slants, driven fundamentally by gravity yet facilitated by immersion with water and by substitute freezing and thawing. Generally not distinguishable with the exception of through expanded perception.
