Explanation:
B. is not a validated bu experimentation
Given:
The length of the string is l = 6 m
The speed of the wave is
Required: Lowest possible frequency for the standing wave.
Explanation:
The lowest possible frequency is the fundamental frequency.
The fundamental frequency can be calculated by the formula
On substituting the values, the fundamental frequency will be
Final Answer: The lowest possible frequency for standing waves on this string is 16.67 Hz
The atom that would least likely form chemical bonds with other atoms would be C. A neon containing 4 valence electrons, this is because neon itself is an inert gas, it would not necessarily react as it already possess the maximum number of electrons needed to achieve stability and have a full octet, even if it is forced to obtain 4 valence electrons it would not react with other atoms.
Answer:
100 Hertz
1,000 Hertz
10,000 Hertz
Explanation:
Humans can detect frequencies between 20 Hz and 20,000 Hz.
