Two loudspeakers are placed side by side a distance d = 4.00 m apart. a listener observes maximum constructive interference while standing in front of the loudspeakers, equidistant from both of them. the distance from the listener to the point halfway between the speakers is l = 5.00 m . one of the loudspeakers is then moved directly away from the other. once the speaker is moved a distance r = 60.0 cm from its original position, the listener, who is not moving, observes destructive interference for the first time. find the speed of sound v in the air if both speakers emit a tone of frequency 700 hz .

It is reasonable to assume that the bulk modulus of blood is about the same as that of water (2.2 gpa). as one goes deeper and deeper in the ocean, the pressure increases by 10000 pa for every meter below the surface. if a diver goes down 80.0 m in the ocean, by how much does each cubic centimeter of her blood change in volume? give the answer in cubic centimeters (actually one cubic centimeter equals one milliliter).
