Question

for resonance which must tally​

Answer 1

Answer:

frequency

Explanation:

Resonance is the phenomeneon that occurs when a physical system is periodically disturbed at the same period of one of its natural frequencies.

Resonance is the tendency of a system to oscillate at maximum amplitude at certain frequencies, known as the system's resonance frequencies

At these frequencies, even small periodic driving forces can produce large amplitude vibrations, because the system stores vibrational energy

Resonant frequency continue, until the energy loss in the physical system due to non-elastic motion equals the energy supplied by the disturbing force. In extreme cases, the system will exceed its limits and self destruct before equilibrium occurs.

Answer 2

answer : option (b) frequency

explanation : resonance occurs when frequency made from outside source of an oscillating system is same as its own natural frequency.

in simple language,

when frequency of a vibrating body is equal to the natural frequency of another body then transfer of energy between the bodies is maximum and other body vibrates with a greater amplitude. This phenomenon is known as resonance.

here it is clear that for resonance frequency must tally.
