Two large speakers broadcast the sound of a band tuning up before an outdoor concert. While the band plays an A whose wavelength is 0.773 m,
Brenda walks to the refreshment stand along a line parallel to the speakers. If
the speakers are separated by 12.0 m and Brenda is 24.0 m away, how far
must she walk between the "loudspots"?

The slope of a velocity time graph over any interval of time gives the during that interval

Researchers determine that the biodiversity in a woodland region is declining. they identify two major threats to the region's biodiversity, a method to address each threat, and the expected outcome of each method. this information is shown in the table. a) reforestation would not benefit many species because most forest species live on the ground. b) reforestation would take the longest time to be effective because trees take several years to grow. c) biological augmentation would benefit only a few species because is is typically not very effective. d) biological augmentation would take less time to ve effective because it targets the majority of prey species.
