The statements that most adequately recount the characteristics of a spring that lies in the position of equilibrium would be:

c). The elastic potential energy is zero.

d). The displacement of the spring is at a maximum.

e). The net force acting on the spring is zero.

Spring reaches the position of equilibrium when the force on the spring, as well as, the mass of the spring is similar in respect to the magnitude yet their directions are opposing one another. In order to allow spring to remain in the state of equilibrium, its elastic capacity(potential) would be zero because the movement remains zero as well. The displacement carried out by the spring would be maximum as it takes it towards the equilibrium position where the mass varies its direction and the velocity turns zero. The net force would also turn zero as the velocity goes zero which implies that no change is taking place in the spring's movement.

Thus, options c, d, and e are the correct answers.

Answer from: GoldenToad7449

The elastic potential energy is zero.

The net force acting on the spring is zero.

Explanation:

The equilibrium position of a spring is the position that the spring has when its neither compressed nor stretched - it is also called natural length of the spring.

Let's now analyze the different statements:

The spring constant is zero. --> false. The spring constant is never zero.

The elastic potential energy is at a maximum --> false. The elastic potential energy of a spring is given by

$E=\frac{1}{2}kx^2$

where k is the spring constant and x the displacement. Therefore, the elastic potential energy is maximum when x, the displacement, is maximum.

The elastic potential energy is zero. --> true. As we saw from the equation above, the elastic potential energy is zero when the displacement is zero (at the equilibrium position).

The displacement of the spring is at a maxi num --> false, for what we said above

The net force acting on the spring is zero. --> true, as the spring is neither compressed nor stretched

Answer from: Quest

hello, i am papaguy.

i have found an answer to your question but use it as information.

information: because weak acids/bases have low concentration of hydrogen ions, the addition of water has a large impact on the ph. 2. a difference in 1 unit is a 10x difference in concentration for example; a liquid with ph of 3 is 10x more acidic than a liquid with a ph of 4. therefore, a liquid with a ph of 3 is stronger.

best of luck!
