Which is a correct description of Hooke’s law?
2 answers:
Answer:
1.The force applied to a spring equals the product of the spring constant and the displacement.
Explanation:
Hooke's law states the relationship between force applied to a spring, spring constant and displacement of the spring, as follows:
where
F is the force applied
k is the spring constant (which represents the stiffness of the spring)
x is the displacement of the spring relative to its equilibrium position (compression or stretching)
From the equation above, we see that the correct answer is
1.The force applied to a spring equals the product of the spring constant and the displacement.

Answer:
it obeys the law of vector addition
Explanation:
In the analytical method, we use the Pythagorean theorem to find the magnitude of the resultant because it obeys the law of vector addition.
The resultant of two vectors A and B is given by;
R' = A' + B'
Therefore, Pythagorean theorem is used if the two quantities are vectors and vector quantities obey the law of vector addition.
