A grunting porpoise emits a sound of 61 Hz sound. What is the wavelength of this sound in water, where the speed of sound is 1500 m/s? Answer in units of m

Calculate the mass of an object that has a momentum of 100kg x m/sec and velocity of 4 m/sec

(1 point) match the differential equations and their vector valued function solutions. you may wish to multiply at least one solution out fully, to make sure that you know how to do it. you can get the other answers quickly by process of elimination and just multiply out one row element.
