    How was Physics 6PH08 Alternative to practical ?

    I I got resonant frequency to be 1.54 Hz, can it be true?

    How was Physics 6PH08 Alternative to practical ?

    Because it's not a given quantity, and since measured there must an uncertainty

    How was Physics 6PH08 Alternative to practical ?

    For resonant frequency, i got 1.54 Hz. Did anyone get a similar answer, because the peak wasn't at 1.6Hz. For that reason we should take for reading of amplitude at different frequencies as the peak was uncertain by varying the variable frequency supply. Am I right??

    How was Physics 6PH08 Alternative to practical ?

    % uncertainty in mean volume was 1.9%, right? because % uncertainty in diameter was 0.4%.Also, i got 1.54 Hz for resonant frequency and observation was that spring would oscillate with maximum amplitude. Am I right??
