A 12 string guitar sounds different from a 6 string guitar based on which effect?

A ukulele has 4 tuning pegs. If you turn them the sound of the strings change. Explain this in terms of the physics vocabulary.

Two musicians are tuning their guitars. When they both try to play the same “E” note,they hear 3 beats per second. The first musician then tightens the string, after which theyhear 2 beats per second. Before the string was tightened, which guitar had a higherfrequency for the note? Explain.

3. This problem is about driven oscillating systems. As we saw in lecture, when a mass-spring system is set in motion (given a tug or a kick) and subsequently left alone, it will oscillate at a frequency that depends on the spring constant and the mass, which is called the natural frequency, wo = However, what if an additional sinusoidal force with arbitrary TTL frequency w is applied? a) Consider a horizontal mass-spring system with an additional horizontal driving force F = Focos (wt) where Fo is a constant. For now, assume wwo. Using Newton's second law, find a differential equation for the position of the mass. b) To solve the differential equation from part a), try a solution with the form x = A cos (wt) where A is a constant. What must A be to solve the differential equation? c) The solution given in part b) shows that the mass can oscillate at the frequency of the driving force instead of its natural frequency. However, notice that the solution in part b) has no arbitrary…
