Explanation Given info: the length of the steel wire is 0.7000 m , mass of the steel wire is 4.300 × 10 − 3 kg . The equation for fundamental frequency of the vibration corresponds to the middle of the musical scale. f c = 1 2 L T m / L Here, f c is the fundamental frequency, L is the string length, T is the string tension, and m is the string mass per unit length. Rewrite the expression to get T . T m / L = 2 L f c T m / L = 4 L 2 f c 2 T = 4 L f c 2 m The expression for tension in the steel wire in a piano is, T = 4 L f c 2 m Substitute 0

Equation of Waves

Wave is an oscillation or disturbance traveling in a medium. It performs the transportation of energy but does not carry any matter. This motion of waves will transport fuel in a medium without permanent transfer of mass (particle).

4 Problem 4) A particle is being pushed up a smooth slot by a rod. At the instant when 0 = rad, the angular speed of the arm is ė = 1 rad/sec, and the angular acceleration is = 2 rad/sec². What is the net force acting on the 1 kg particle at this instant? Express your answer as a vector in cylindrical coordinates. Hint: You can express the radial coordinate as a function of the angle by observing a right triangle. (20 pts) Ꮎ 2 m Figure 3: Particle pushed by rod along vertical path.
