Geiger-Muller tube is instruments requires you test three times the background of the work area.
<u>Explanation</u>:
These detectors are gas filled detectors and hence requires time for responding to the value. This time is taken because during this period it collects the electric charges and features of the electric circuit. It also gets stabilized during this period. This device has thumb rule i.e one must wait or hold for at the least 3 times the time constant before getting the precise and accurate reading. The time constant order is 10 seconds for the ionization chamber but for the Geiger counter it can vary from seconds to greater than 20 seconds
Answer:
Scientists use creativity to determine which smaller questions are likely to yield results, imagine possible answers to their questions, and devise ways to test those answers.
Explanation:
A team of scientists has consistently gotten the same unexpected results from a set of experiments. Then "Peer review of the scientific methods and data analysis" may helps the scientists to ensure the reliability of the results.
<u>Answer:</u> Option D
<u>Explanation:</u>
The roots of achieving unexpected results lie or depend on scientific methods used and analysis of data performed for acquiring results. Therefore when experiment results into unexpected readings researcher need to give a review of entire method and analysis.
Although rest other points like publication of results, discussing with friends and family members or removal of inconsistent data may or may not help depends upon conditions but reviewing helps as observed in many cases , because one must have performed unintentionally or intentionally an error while going through methods.
