Answer:
Creep
Explanation:
Creep is a type of deformation that occurs when continuous and long term mechanical stresses are being subjected to a material. Material deformation is observed even if the stresses are below the yield strength of the material, . The effect of creep is more pronounced if there is an application of heat.
In a study of turbine blades it has been shown that at the location where creep is present there was micro-structural degradation. In other places there was no micro-structural degradation.

The acceleration of the baseball is:
where
and
are the final and initial speed of the ball, and
is the time interval in which the force acted.
Replacing the numbers, we get
And at this point, we can use Newton's second law F=ma to find the value of the force of the pitching machine:
The precision of the measuring instruments will be 2.5%.
<h3>What is precision?</h3>
It should be noted that precision simply means how close a test result will be when it's repeated.
In this case, the precision of the measuring instruments will be:
= (2 - 1.95)/2.
= 0.05/2
= 2.5%
Therefore, the the precision of the measuring instruments will be 2.5%.
