Answer:
Option (D) i.e., s1.getClassRank( ); is the correct option to the following question.
Explanation:
Here, in the following option, the object "S1" is the object of the class "rank" and "getClassRank( )" is the function of that class "rank". so, in the following code the function "getClassRank( )" is called through the class object which computes and returns the class rank of the students.
So, that's why the following option is the correct way to call the function.
Answer:
B) Developer is poured down the drain while fixer can be reduced
Explanation:
The effluents produced during photographic processing includes, wash water, bleach, fixer, and developer
The developer is an alkaline solution, with a pH of approximately 10.0, while the pH of the fixer is about 4.3, it is therefore, acidic
The rate of discharge of the developer to the fixer is 2 to 1, and the exhausted developer, fixer and process effluents combined are neutral and can be handle by the the treatment works and the drain pipes
Fixer which remain clear can be reused for more than a day, while the spent basic Developer and the acidic Spent Stop Bath can be combined to form a neutral solution, having a pH of approximately 7, which make them less hazardous to be disposed off down the sink into the drain
Therefore, <em>developer is poured down the drain while fixer can be reused</em>
I guess the correct answer is information processing
Infοrmatiοn prοcеssing is thе changе (prοcеssing) οf infοrmatiοn in any mannеr dеtеctablе by an οbsеrvеr. As such, it is a prοcеss that dеscribеs еvеrything that happеns (changеs) in thе univеrsе, frοm thе falling οf a rοck (a changе in pοsitiοn) tο thе printing οf a tеxt filе frοm a digital cοmputеr systеm.
The scene of a human sitting at a computer terminal, responding to stimuli flashed on the computer screen, would most likely be described as depicting an information processing experiment.
