30. Which one of the following experimental errors can be reduced by taking repeated
measurements?
A. Zeros errors B. Parallax errors
C. Systematic errors
P.
Random errors



Answer :

Final answer:

Random errors in measurements can be reduced by taking repeated measurements to minimize their impact on accuracy.


Explanation:

Random errors are the statistical variability of measured numbers that vary from one observation to another. Taking repeated measurements helps to minimize random errors as they cancel out when many measurements are averaged. By averaging multiple measurements, the accuracy can be improved, bringing the average value closer to the actual value.
