An unfingered guitar string is 0.68 m long and is tuned to play E above middle C (330 Hz). Required:

a. How far from the nut of the guitar must a fret (and your finger) be placed on this string to play B (494 Hz)?

b. What is the wavelength on the string of this 466-Hz wave?

c. What is the frequency of the sound wave produced in air at 18°C by this fingered string? The speed of sound in air is v≈(331+0.60T)m/s, where T is the temperature in ∘C.

d. What is its wavelength of the sound wave produced in air at 18°C by this fingered string?

Simple machines can a. increase force only b. decrease force only c. increase or decrease force

Amass attached to a spring is displaced from its equilibrium position by 5cm and released. the system then oscillates in simple harmonic motion with a period of 1s. if that same mass–spring system is displaced from equilibrium by 10cm instead, what will its period be in this case? a mass attached to a spring is displaced from its equilibrium position by and released. the system then oscillates in simple harmonic motion with a period of . if that same mass–spring system is displaced from equilibrium by instead, what will its period be in this case? a) 0.5sb) 2sc) 1sd) 1.4s

At 20∘c, the hole in an aluminum ring is 2.800 cm in diameter. you need to slip this ring over a steel shaft that has a room-temperature diameter of 2.804 cm . 1. to what common temperature should the ring and the shaft be heated so that the ring will just fit onto the shaft? coefficients of linear thermal expansion of steel and aluminum are 12×10−6 k−1 and23×10−6 k−1 respectively.
