Find the ratio of the tension in the wire before and immediately after the string is...
Part A) After the system is released, find the horizontal tension in the wire. Part B) After the system is released, find the vertical tension in the wire. Part C) After the system is released, find the acceleration of the box. Part D) After the system is released, find the magnitude of the horizontal and vertical components of the net force that the acle exerts on the pulley. A 12.0-kg box resting on a horizontal, frictionless surface is attached to...
A stretched wire has a fundamental frequency νgw. If the wire is cut to 80% of its length and the tension is increased by 60%, what is the ratio of the new fundamental frequency to that of the old?
Problem 2 A stretched wire has a fundamental frequency v, gw If the wire is cut to 65% of its length and the tension is increased by 10%, what is the ratio of the new fundamental frequency to that of the old?
A block of mass M is suspended by a massless wire of length L and, after a completely inelastic collision with a bullet of mass m, swings up to a maximum height y < L. Find: (a) the speed v of the block with the bullet in it immediately after impact; (b) the tension force T in the wire immediately after impact; (c) the initial horizontal velocity vo of the bullet. Explain pendulum tension please.
12. [1pt] A piano wire is stretched to a tension of 330 N. A wire is just a string made of metal. If the wire is 1.76 m long and has a total mass of 0.250 kg, what is the phase speed of transverse waves travelling along this wire?
A.) Determine the tension in the cord before the string is burned B.) Show that the cord, strong enough to support the object before the string is burned, is also strong enough to support the object as it passes through the bottom of the swing C.) The motion of the pendulum after the string is burned is periodic. Is it also simple harmonic? why or why not? Cord p 60° String A pendulum consists of a small object of mass...
A stretched wire has a fundamental frequency νgw. If the wire is cut to 45% of its length and the tension is increased by 20%, what is the ratio of the new fundamental frequency to that of the old?

A uniform steel piano string of length 5 feet is under a tension of 900 pounds throughout its length. The wire has linear density 0.027 lb/ft and cross sectional radius of 0.05 in. (a) Calculate the velocity of transverse waves in the string, c. (b) What is the fundamental frequency of vibration of this string? A uniform string with length L under tension is plucked at x = L/3 with an amplitude h and released. Find the resulting motion y(x,t).
