A science student takes 100 observations in an experiment. Second time he takes 600 observations in the same experiment .By doing so the possible error becomes:

A research worker takes 100 observations in an experiment . If he repeats the same experiment by taking 500 observation , how is the probable error affected?

A physical performs an experiment and taken 200 readings. He repeats the same experiment and now takes 800 readingbs. By doing so

A scientist performs an experiment in order to measure a certain physical quantity and takes 100 observations. He repeats the same experiment and takes 400 observations, by doing so

When 10 observations are taken, the random error is x , When 100 oberservations are taken, the random error becomes

Two strings of same material are joined to form a large string and is stretched between rigid supports. The diameter of the second string is twice that of the first. It was observed in an experiment that the whole string was oscillating in 4 loops with a node at the joint. Find the possible lengths of the second string if the length of first string is 90 cm.

A student performed the experiment of glass slab and with different angles of incidence measured the angles of refraction and emergence in each case. He then recorded his observations as given in the table. The correct observation is :

A student is working on a science project and is going through each step of the scientific method after the student conducts his or her first experiment and records the result of the experimental test what according to you should the student do next

If all measurements in an experiment are taken up to the same number of significant figures , then mention two possible reasons for maximum error.
