Scientists are investigating how well different microphones capture and record sounds. They use tools that show how loud the high and low sounds are and a tool that shows how much noise is recorded along with the actual sounds. Which is a scientific question that could be included in this investigation? Which microphone captures a singer's low sounds the loudest? Which microphone sounds best for a female singing rock music? Which microphone best records high sounds and low sounds? Which microphone is usually a male singer's favorite?

Which microphone captures a singer's low sounds the loudest?

Explanation:

Scientific questions are the basis of any scientific experiment. An observation is followed by a scientific question. In this question, scientists are investigating how well different microphones capture and record sounds by using tools that show how loud the high and low sounds are and a tool that shows how much noise is recorded along with the actual sounds.

Hence, a scientific question should be that which will cover the whole aspect of the investigation i.e. the question should contain a general scope of the problem. Hence, a scientific question that could be included in this investigation is:

Which microphone captures a singer's low sounds the loudest?

This is because this question contains every part being investigated i.e. How different microphones capture sounds and records them (whether low or high).

r=rho l/a where a is the area, l is the length and rho is resistivity so the greater the area the lesser the resistance thats why the earth pin is thicker bcos current follow the shortest path, so less resistive .
