How does peer review affect research? O A. Experimental results will be trusted by the scientific community
only if they have been peer-reviewed,
B. Experimental results are possible only if they have been peer
reviewed
C. An experiment will not be repeated by others if it has been peer-
reviewed
D. Experimental results will be published only before they have been
peer reviewed

c. because step up transformer steps up the input voltage i.e increases the input voltage  

the number of turns are greater on the secondary side of step up transformer  

transformer does not handle dc current

answer: option (a) is the correct answer.

explanation:

the measurement of hydrogen ions in a solution is known as ph.

if ph of a solution is less than 7 then the solution is acidic. if ph of a solution is greater than 7 then the solution is basic.

when the ph of a solution equals 7, then the solution is considered as neutral.

the ph of pure water is 7, therefore, it means that concentration of hydronium ions equals that of hydroxide ions.
