Question

A stroboscope was used to determine the frequency of the string
oscillator. Strobe frequencies *f _{s}* were recorded
where a single stationary image of the oscillating string was
observed. The frequency of the oscillator

Strobe Frequency
f_{s}Hz |
Oscillations per flash n |

22.9 | m |

15.2 | m+1 |

11.8 | m+2 |

8.8 | m+3 |

m an integer, is determined to be 2.

The oscillator frequency is determined to be *f* = 45.65
Hz, from the average of *nf _{s}*.

Use the mean error technique to determine the uncertainty
*f*. Express the answer to two decimal places, with the SI
unit included.

Answer #1

A stroboscope was used to determine the frequency of the string
oscillator. Strobe frequencies fs were recorded
where a single stationary image of the oscillating string was
observed. The frequency of the oscillator f can be
determined from the stroboscope frequencies fs
by f = nfs where n is an
integer corresponding to the number of oscillations per flash. The
strobe frequencies produced were determined and tabled below:
Strobe Frequency

11. A simple pendulum undergoes small-angle oscillations. Which
of the following pairs (mass, string length) will oscillate with a
period greater than 2.2 seconds?
a) (0.50 kg, 1.0 m)
b) (0.40 kg, 0.80 m)
c) (1.0 kg, 0.50 m)
d) (0.80 kg, 0.40 m)
e) none of the above answers are correct
(numbers 15-17) An ideal horizontal spring-mass system begins
oscillation with the mass at x=0 (the spring is relaxed) and moving
in the -x direction at 6.00 m/s. The...
