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
In order to make the proton gradient, protons are pumped across the mitochondrial membrane at several points in the electron transport chain. However, that proton gradient is only used to make ATP by the ATP synthase, which is technically separate from the electron transport chain.
Answer:
The answer is sedimentary rock.
Explanation:

Hope that it helps!
