Which of the following scenarios describes a condition in which resonance can occur? A. Two tuning forks that vibrate at the same frequency are near each other. One tuning fork is struck with a mallet so that it vibrates. B. Two tuning forks are struck simultaneously, one with a frequency of 659Hz and one with a frequency of 639 Hz, causing beats. C. A tuning fork is over a column of air that is 9/2 the wavelength of the wave produced by the tuning fork. D. An isolated tuning fork is struck with a mallet, causing it to vibrate strongly at 659 Hz.

It is not C

Resonance describes the phenomenon of increased amplitude that occurs when the frequency of a periodically applied force is equal or close to a natural frequency of the system on which it acts.

The resonance depends on the following:-

According to the question, Resonance is the condition when the frequency of an object vibrates at a frequency due to the action of the force.

It is equal with the natural frequency of another object and the system starts to vibrate with higher frequency and amplitude than the frequency of the object subjected to an external force.

Option A is correct because resonance occurs when two tuning forks vibrating at a same frequency are brought close to each other as described in option A.

The correct answer is A

Explanation:

i feel your pain too because i cant find my dad and hes been missing for 17 years of my life

explanation:

he went to the supermarket with your dad

we need to know the time interval during which the force acts. impulse of force = momentum change
