12. A Barton's pendulum (shown below) can be used to demonstrate the phenomenon of mechanical resonance. It essentially consists of multiple pendula hung from the same anchor object. On the Barton's pendulum apparatus shown below, the mass labelled X is pulled back and released, setting it in oscillatory simple harmonic motion. All masses are attached to the same string, and therefore a periodic force caused by pendulum X's simple harmonic motion is transferred to each of the other pendula. In other words, pendulum X exerts a force on the other pendula each time it completes an oscillation cycle. Once pendulum X begins to oscillate, the result will be that Choose the option below that correctly completes the above statement. OOO E D A. no other pendula will move because they all have a smaller mass attached than pendulum X B. pendulum C will begin to oscillate the most because this pendulum has the same length as pendulum X C. pendula A and B will begin to oscillate the most because these pendula have longer lengths than pendulum X D. pendula D and E will begin to oscillate the most because these pendula have shorter lengths than pendulum X

Transcribed Image Text:12. A Barton's pendulum (shown below) can be used to demonstrate the
phenomenon of mechanical resonance. It essentially consists of multiple
pendula hung from the same anchor object.
On the Barton's pendulum apparatus shown below, the mass labelled X is
pulled back and released, setting it in oscillatory simple harmonic motion. All
masses are attached to the same string, and therefore a periodic force
caused by pendulum X's simple harmonic motion is transferred to each of
the other pendula. In other words, pendulum X exerts a force on the other
pendula each time it completes an oscillation cycle.
Once pendulum X begins to oscillate, the result will be that
