Calculate the intensity of the sound at r1. Calculate the sound intensity level at r2. Calculate the power of the sound source. How much energy per second is delivered to your eardrum from this sound wave at r1, if your eardrum has an area of 0.96 x 10-5 m2

Two 1.20-m nonconducting wires meet at a right angle. one segment carries + 2.50 µc of charge distributed uniformly along its length, and the other carries - 2.50 µc distributed uniformly along it, as shown in fig. 21.50. ( a. find the magnitude and direction of the electric field these wires produce at point p, which is 60.0 cm from each wire. ( b. if an electron is released at p, what are the magnitude and direction of the net force that these wires exert on it?
