If they have the same tension and length, will a thicker or a thinner guitar string sound higher in frequency? Why?
Answer to relevant QuestionsA child’s swing (a pendulum) has only one natural frequency, f1, yet it can be driven or pushed smoothly at frequencies of f1/2, f1/3, and 2f1. How is this possible? One simple harmonic motion is described by a sine function, y = A sin (wt), and another is described by a cosine function, y = A cos(wt). Discuss the differences in their initial position, velocity, and acceleration. A 0.350-kg block moving vertically upward collides with a light vertical spring and compresses it 4.50 cm before coming to rest. If the spring constant is 50.0 N/m, what was the initial speed of the block? (Ignore energy ...A breeze sets a suspended lamp into oscillation. If the period is 1.0 s, what is the distance from the ceiling to the lamp at the lowest point? Assume that the lamp is a point mass and acts as a simple pendulum. The velocity of a vertically oscillating mass–spring system is given by v = (0.65 m/s) sin [(4 rad/s)t]. Determine (a) The amplitude and (b) The maximum acceleration of this oscillator.
