Two identical loudspeakers that are 5.00 m apart and face toward each other are driven in phase by the same oscillator at a frequency of 875 hz. the speed of sound in the room is 344 m/s. if you start out standing midway between the speakers, find the shortest distance you can walk toward either speaker in order to hear a minimum of sound.

0.0982 m

Explanation:

Given

distance between two loudspeaker is 5 m

frequency (f )=875 Hz

speed of sound (v)=344 m/s

Let be the smallest distance moved by observer then

Position of observer w.r.t to first speaker is

Position of observer w.r.t to second speaker is

For Destructive interference

For minimum m=0

and

a and b sometimes have a positive value

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.
