What does it mean for a hypothesis to be testable? O A. It must be able to reject biased data.
O B. It must be supported by peer review.
O C. It must be able to be supported or refuted by data.
O D. It must be what the scientist is hoping is the result.

resonant frequency

initial speed when it is dropped is 150 ft/s

now at the same moment the acceleration due to gravity is perpendicular to its velocity

so as we know that

now we have centripetal acceleration a = 32 ft/s^2 as its perpendicular to velocity

while tangential acceleration at the same moment will be zero

so

now radius of curvature is given as

so the radius of curvature just after it is dropped is 703.125 ft
