Question

1.
अनुनाद के लिए समान होना चाहिए।
For resonance which must tally.
(a) आयाम (Amplitude) (b) आवृति (Frequency)
(C) वेग (Velocity)
(d) कला (Phase)
​

Answer 1

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.

Answer 2

The correct answer is Option b (Frequency).

Explanation:

• If the frequency of such a object (vibrating) is equivalent to something like the normal frequency of some other object, the energy exchange between some of the entities is optimum as well as the other object is more amplitudinally vibrated. This effect is termed as Resonance.
• It happens whenever the frequency of such an oscillatory device produced from outside reference would be the same as one's frequency response.

Another three choices relating to the specified scenario are not. So the second option seems to be the correct answer to that.
