A string of length 0.650 m and a linear density of 2.02 x 10-3 kg/m is vibrating in the fundamental harmonic mode even as the tension is increased over time. How many oscillations does the string go through from t = 0 to t = 4.26 s if the tension is expressed as T = a + 18.0 N, b = 12.0 kg m/s, and c = 2.13 s? bt where a = Enter a number. is increased, the frequency will change. The number of oscillations is the integral sum of all the frequencies over the time period over which the tension changes, which is the same as integrating the given function over the appropriate limits. cycles Additional Materials Reading Tutorial Show My Work (Optional) ?
