where you stand 20. m from the speaker that is
outputting 170 watts is this.
26You are standing this far away from an 80.0 W
stereo system if the intensity of the sound
where you stand is 1.37 W/m2
27A rock is dropped from a sea cliff and the sound
of it striking the ocean is heard 3.4s later. If
the speed of sound is 340 m/s, how high is the
cliff?
