Interval PQ represents: {Ans: period/2}Two stationary tuning forks (350 and 352 Hz) are struck simultaneously. The resulting sound is observed to: {Ans: frequency of 2 beats/s}an "A" note played on a violin string. Let the subscript "s" refer to the violin string and "a" refer to the air. Then: {Ans: fs =fa but λs ≠λ a}Let f be the frequency, v the speed, and T the period, relationship? {Ans: f=1/T}triple point (273.16 K) the pressure is 6.30 × 104 Pa. For this thermometer a kelvin corresponds to a change in pressure of about: {Ans: 2.31 × 102 Pa}which might NOT vanish over one cycle of a cyclic process? {Ans: energy absorbed by the substance as heat}A 30-cm long string, with one end clamped and the other free to move transversely, is vibrating in its second harmonic. The wavelength of the constituent traveling waves is: {Ans: 40cm}time that latent heat is involved in a change of state: {Ans: temperature does not change}wavelength of 3.0m. The distance from a compression center to the adjacent rarefaction center is: {Ans: 1.5m}y(x, t) = 0.1 sin(3x − 10t). The angular frequency is: {Ans: 10 rad/s}sound
