Answer:
Size is not considered a physical property because it is not measurable with concrete data, but a compound of height, weight and volume, which are physical properties by their own.
A physical property is, according to an initial understanding, an individual property, that is, which is linked in particular to any substance.
A physical property has the characteristic of being able to be measured or observed without affecting the composition or integrity of the respective substance. Some examples of physical properties are mass and volume.
The product of
(wavelength) times (frequency)
is always the wave’s speed.
In this problem, you are asked to find a vertical position of a ball when you are given its initial position on a spring. In both locations, the speed of the ball is zero.
If non-conservative forces are either known or small and if energy is converted from one form to another between the locations, then any time you relate speed and position of an object at two different points, conservation of energy is the most direct way to understand the problem.
In this case, you start out with stored energy in the compression of the spring and convert it to stored gravitational energy.
The answer is having fewer neutrons than protons or electrons.
