Many animals like dolphins and bats utilize sonar (echolocation) to determine
where objects are positioned. What
behavior of waves do these animals take
advantage of?

What is the relationship between the wavelength of a wave and it's energy?

Acoyote chasing a rabbit is moving 8.00 m/s due east at one moment and 8.80 m/s due south 4.25 s later. let the x axis point due east and the y axis point due north. find the direction of the coyote's average acceleration during that time.

If there's a small amount of friction between two surfaces, the result could be select all that applya. no movement b. heatc. a little bit of movementd. sliding around
