You want to create standing  waves in a string of length 1.50 m, by attaching different masses on the end of the string passing over the pulley. frequency is 60.0 Hz. Assuming the linear mass density of  the string is 3.5 × 10−4/, what masses should you hang on the string to produce standing waves of  the first, second and fifth harmonics?

Current supplied to consumers from generating plants like coal power plant, nuclear power plant, geothermal and others are in form of alternating current instead of direct current because it can be transported easily in a long distance. also, the alternating current has a wide range of frequency and the amount or energy can be increased or decreased.
