Question: A sound wave with intensity 9 mW/m2 interferes destructively with a sound wave that has an intensity of 13 mW/m2.
Part A- What is the intensity of the superposition of the two?
If possible just a brief explanation how you got the answer?
Now consider this applet, where the two blocks have different masses. Plug the starting values into your formula from Part G, using 5 for mass of the red block and 10 for the magnitude of the acceleration of gravity.
