A guitar string of mass mm under tension resonates in its fundamental mode outside the ear canal and the string produces resonance in the ear's fundamental mode and so is perceived at maximum loudness. A second guitar string of different mass but of the same length and under the same tension again vibrates in the fundamental mode. The new string is designed to produce a resonance in the next higher harmonic of the ear. What should be the mass of the the new string in terms of the original mass mm

What’s #16 asking and how do i solve it?

Consider a uniformly charged ring in the xy plane, centered at the origin. the ring has radius a and positive charge qdistributed evenly along its circumference. a)what is the direction of the electric field at any point on the z axis? . b)what is the magnitude of the electric field along the positive z axis? use k in your answer, where k=14πϵ0. d)the ball will oscillate along the z axis between z=d and z=−d in simple harmonic motion. what will be the angular frequency ω of these oscillations? use the approximation d≪a to simplify your calculation; that is, assume that d2+a2≈a2. express your answer in terms of given charges, dimensions, and constants
