Answer #1

Bulk modulus will decide the speed of sound ... More is speed more larger distances it travel ... More is bulk modulus more it travels ...

Theatre has large halls and as actor play live there we need to have larger bulk modulus in theatre than cinema

B) wave travels in theatre reflection for larger distance and material is designed for the wall in such a way that it will make constructive interference so that person sitting away can hear the sound . But in cinema multiple speaker are placed at different places making sound to travel directly without reflection ... And even after reflection sound will destructively interference so the no echo will come

A SCUBA diver produces a spherical air bubble with bulk modulus B = 1.2 x 105 Pa and radius r1 = 2.9 mm while exploring a shipwreck below the surface of the ocean. The air bubble rises to the surface of the ocean and expands to a radius r2  = 3.8 mm. What is the difference in pressure between the surface and at the SCUBA diver's depth, ( Psurface − P diver )?

It is reasonable to assume that the bulk modulus of blood is about the same as that of water (2.20 GPa ). As one goes deeper and deeper in the ocean, the pressure increases by 1.0×104Pa for every meter below the surface A) If a diver goes down 33.0 m (a bit over 100 ft ) in the ocean, by how much does each cubic centimeter of her blood change in volume? B) How deep must a diver go so...

Sound in water travels at a velocity governed by the relation v = √(B/ρ) where B is the bulk modulus and ρ is the density. For salt water, take B = 2.31 × 109 Pa and ρ = 1063 kg/m3. A whale sends out a high frequency (1 kHz) song to another whale 1.0 km away. How many wavelengths fit between the whales? How much time, in seconds, does it take for the sound to travel between the whales, t?
