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.
Answer:
T = 2.82π s
x = Acos(0.71t)
Explanation:
This problem can be solved by using the expressions
( 1 )
( 2 )
where T is the period of oscillation of the system, m is the mass of the object attached to the spring, k is the spring constant and x is the position of the object.
By replacing in the expression (1):

Taking 6 inches as the amplitude of the motion, we have
