The first five harmonics for a vibrating string are shown in Figure24.13.a. For each harmonic, identify the number of wavelengths represented. b.For each harmonic, identify the number of nodes and antinodes that are present (include the ends of the string in your count).c. Which of the five harmonics has the highest natural frequency?d. Make a drawing that shows what the sixth harmonic would look like.

If a substance is in the gas phase, which of qualities of the gas will stay constant? a: volume b: mass c: shape d: position of particles

When a vertical beam of light passes through a transparent medium, the rate at which its intensity i decreases is proportional to i(t), where t represents the thickness of the medium (in feet). in clear seawater, the intensity 3 feet below the surface is 25% of the initial intensity i0 of the incident beam. what is the intensity of the beam "10" feet below the surface? (give your answer in terms of i0. round any constants or coefficients to five decimal places.)

A1000-kg car is moving at 30 m/s around a horizontal unbanked curve whose diameter is 0.20 km. what is the magnitude of the friction force required to keep the car from sliding?
