Answer:
metal
Explanation:
sound can travel best in materials with higher elastic properties like metal than it can through other solids like plastic or rubber which have lower elastic properties
I hope this helps
So??
what is the question??
The rms potential difference is defined as the peak value of the potential difference divided by the square root of 2:
where
is the peak value of the voltage (the maximum voltage).
The generator in our problem has a maximum voltage of
, so its rms potential difference is
