The correct Answer is:
To solve the assertion and reason question, we will analyze both the assertion and the reason step by step. ### Step 1: Understand the Assertion The assertion states that "the skill in swinging to greater heights lies in the synchronization of the rhythm of pushing against the ground with the natural frequency of the swing." - **Explanation**: When a person swings, they can increase their height by timing their pushes with the natural frequency of the swing. This means that if the timing of the pushes matches the swing's natural oscillation, the swing will gain more energy and reach greater heights. ### Step 2: Understand the Reason The reason provided is "the phenomenon behind this is resonance." - **Explanation**: Resonance occurs when an external force is applied at the same frequency as the natural frequency of a system. In the case of swinging, when the pushes (external force) match the swing's natural frequency, the swing experiences maximum energy transfer, leading to increased amplitude (height). ### Step 3: Evaluate the Truth of the Assertion - The assertion is true because the synchronization of pushing with the swing's natural frequency indeed allows for greater heights. ### Step 4: Evaluate the Truth of the Reason - The reason is also true because resonance is the phenomenon that explains why matching the frequency of the pushes with the swing's natural frequency leads to increased amplitude. ### Step 5: Determine the Relationship - Since both the assertion and reason are true, and the reason correctly explains the assertion, we conclude that the correct option is that both the assertion and reason are true, and the reason is a correct explanation of the assertion. ### Final Conclusion Both the assertion and reason are true, and the reason is a correct explanation of the assertion.
