Optical glass is usually free of strain, but when mechanical or thermal stress is exerted upon it, glass shows birefringence. Stress F (Pa), optical path difference (nm) and thickness of glass d (cm) have the following relationship:
In this case, proportional constant is called the photoelastic constant. It is listed in this catalogue at a unit of (nm/cm/105 Pa). The photoelastic constant is the material constant that will change by glass type. By using it, optical path difference can be computed from given stress. Internal stress can also be computed from optical path difference.
A constant is a variable that always stays the same, e.g. A factor in a controlled experiment that doesn't change.
The definition of acceleration is: Any change of velocity, that is, speed or direction of motion. If an object is undergoing constant acceleration, then the definition says that its velocity must be changing.
No. The definition of acceleration is change in velocity.
No. The definition of acceleration is the change in an object's velocity over time. Acceleration must then be zero since velocity remains constant.
Zero rate of change of velocity. Straight-line motion at a constant speed.
i believe that the definition of a constant multiplier is when you are obviously multiplying thing more than once
the definition is when individuals in a reproduce at a constant rate
Bahnzeitkonstante
Unmoving, resolute, unchanging
It is motion in a straight line at a constant velocity.
A number without a variable. Ex.) 5 is a constant, 5x is not.
erosion
The state of being in proportion.
Not sure about a defention, but the definition is something which does not change.
The thing that never changes
One definition of the derivative is: "Rate of change". Since a constant is constant, it doesn't change, and the rate at which it changes is zero.
It means if it is the constant rate of a number kind of like a direct variation. Like if you say 10 divided by 5 it equals 2 and if you say 4 divided by 2 it equals 2 so that's constant I hope I could help you
