B. The surface of a silver cup turns black when it is exposed to air.
The statements describe a spring at its equilibrium position is the elastic potential energy is zero, the displacement of the spring is at a maximum and the net force acting on the spring is zero.
<h3>What is the equilibrium position?</h3>
A body is in equilibrium when the sum of all forces acting on it equals zero. According to Newton's First Law, when resulting from the laws that act on a body that remains in a state of restriction or in motion in its motion, it remains uniformly null.
In this case the only statements that match the definition of equilibrium position are:
- The elastic potential energy is zero.
- The displacement of the spring is at a maximum.
- The net force acting on the spring is zero.

A + B = Products
This is the correct mechanism.
Answer:
2x10⁻⁴cm and 7.9x10⁻⁵ inches
Explanation:
Micrometer, μm, is an unit of length. Could be related with another units of lenght as, for example:
1.0μm = 1x10⁻⁴cm
1.0μm = 3.93701x10⁻⁵ inches
That means, 2.0μm are:
2.0μm * (1x10⁻⁴cm / 1μm) = 2x10⁻⁴cm
And:
2.0μm * (3.93701x10⁻⁵ inches / 1μm) = 7.9x10⁻⁵ inches
