One fallacy students and researchers often make is expecting to improve the overall performance of a computer just by improving only one aspect of the computer. Instructions are classified as: Integer, Floating Point, Load/Store, Branch, in this fictitious processor. Consider a computer running a program that requires 250s, with 80s spent executing Floating Point (FP) instructions, 60s executed Load/Store instructions, and 50s spent executing branch instructions. a. By how much is the total time reduced if the time for the FP operations is reduced by 20%

Which of the following physical laws can make the flow of water seem more realistic? a. motion b. gravity c. fluid dynamics d. thermodynamics

What statement best describes operating systems? it’s possible for modern computers to function without operating systems. most operating systems are free or very inexpensive. operating systems are managed by the computer’s microprocessor (cpu). operating systems manage the computer’s random access memory (ram).

Write a function balancechemical to balance chemical reactions by solving a linear set of equations. the inputs arguments are: reagents: symbols of reagents in string row array products: symbols of products in string row array elements: elements in the reaction in string row array elcmpreag: elemental composition of reactants in two dimensional numeric array elcmpprdcts: elemental composition of prducts in two dimensional numeric array hint: the first part of the problem is setting up the set of linear equations that should be solve. the second part of the problem is to find the integers from the solution. one way to do this is to mulitiply the rational basis for the nullspace by increasing larger integers until both the left-and right-side integers exist. for example, for the reaction that involves reacting with to produce and : reagents=["ch4", "o2"]; products =["co2", "h2o"]; elements =["c","h", "o"] elcmpreag=[1,4,0;
