Explanation The expression to calculate the beats is, f beat = | f 1 − f 2 | Here, f 1 is the frequency of one interfering wave. f 2 is the frequency of second interfering wave. Beats occurs when the waves of slightly different frequencies interfere. In the piano the keys along the minor chords and major chords produce same frequency of the sound waves

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).

Calculate the anti-clockwise torque and the clockwise torque of the system with the ruler and the washers. Record these values in Data Table 5. Ruler = 11.56 g, small washer = 1.85 g, large washer = 24.30 g. Calculate the % Difference in the Torques and record the values in Data Table 5. Is ΣAnticlockwise torque and Anticlockwise torque the same thing, are they solved in the same way?

A window washer stands on a uniform plank of mass M = 142 kg and length l = 2.80 m supported by 2 ropes attached at the ends of the plank. The window washer has a mass m = 68.0 kg. What is the tension in each of the ropes, T1 and T2, if the window washer's displacement from the center of mass of the plank is x = 0.930 m as shown in Figure 1: Window Washer Problem?
