Alistener is sitting somewhere on the line between two loudspeakers that are 10 m apart. the speakers are each emitting a sine wave with the same frequency and no initial phase difference. the listener finds that the sound is completely cancelled when he is at a distance of 3.5 m from one of the speakers. what is a possible frequency of the sound?

Asolid round steel rod 6.25 mm in diameter and 375 mm long is rigidly bonded to the end of solid square brass rod 25 mm on a side and 300 mm long. the geometric axes of the bare are along the same line. an axial tensile force of 5.4 kn is applied at the extreme ends of the assembly. for steel e = 200 gpa and for brass e = 90 gpa. determine the total elongation for the assembly.

Which of the following is not a transverse wave? a) soundb) lightc) radiod) all of thesee) none of these
