Life is based on carbon; substances in organic chemistry where carbon is a key element is the organic chemistry analysis. The characteristics of carbon make it the cornerstone of organic molecules that make up living substances. Carbon can create really lengthy interlocking chains of C-C bonds. It helps carbon to form the foundation of carbon-containing organic compounds, the base of all established organic livelihoods.

poizon [28]

Answer:

391.67Hz

Explanation:

The fundamental frequency formula in string is expressed as;

Fo = V/2L

V is the velocity of the wave = 329m/s

L is the length of the string = 42cm = 0.42m

Substitute

Fo = 329/2(0.42)

Fo = 329/0.84

Fo = 391.67Hertz

Hence the  fundamental frequency of a mandolin string is 391.67Hz
