Physics, and natural science in general, is a reasonable enterprise based on valid experimental evidence, criticism, and rational discussion. It provides us with knowledge of the physical world, and it is experiment that provides the evidence that grounds this knowledge. Experiment plays many roles in science. One of its important roles is to test theories and to provide the basis for scientific knowledge.[1] It can also call for a new theory, either by showing that an accepted theory is incorrect, or by exhibiting a new phenomenon that is in need of explanation. Experiment can provide hints toward the structure or mathematical form of a theory and it can provide evidence for the existence of the entities involved in our theories. Finally, it may also have a life of its own, independent of theory. Scientists may investigate a phenomenon just because it looks interesting. Such experiments may provide evidence for a future theory to explain.
 
        
             
        
        
        
In prison systems, work release programs are done for the purpose that allows prisoner to leave confinement and to continue working at their current place of employment but would have to return to prison once the shift is done. This can only be given to those prisoners who can already be trusted. Work release programs are done so that these prisoners can still be productive despite of being confined. Hope this answer helps.
        
             
        
        
        
8*2=16
38-16= 22
22/2=11
11 cm is the length of the paper.
I hope this helps!
