They seem to cancel each other out which is odd
Answer:
im pretty sure its c the third answer i got that one right
Explanation:
your welcome :)
-- In combination with 610 Hz, the beat frequency is 4 Hz.
So the unknown frequency is either (610+4) = 614 Hz
or else (610-4) = 606 Hz.
In combination with 605 Hz, the beat frequency will be
either (614-605) = 9 Hz or else (606-605) = 1 Hz.
-- In actuality, when combined with the 605 Hz, the beat
frequency is too high to count accurately. That must be
the 9 Hz rather than the 1 Hz.
So the unknown is (605+9) = 614 Hz.
The trampoline one would be for the elastic answer, the chemical one would be for the chemical answer, and the last one would be for the gravitational one :)
