Male rana catesbeiana bullfrogs are known for their loud mating call. the call is emitted not by the frog's mouth but by its eardrums, which lie on the surface of the head. and, surprisingly, the sound has nothing to do with the frog's inflated throat. if the emitted sound has a frequency of 262 hz and a sound level of 84 db (near the eardrum), what is the amplitude of the eardrum's oscillation? the air density is 1.21 kg/m3 and the speed of sound is 346 m/s.

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?
