Dogs are able to hear much higher frequencies then humans are capable of detecting. For this reason the crystals that are inaudible to the human ear can be heard easily by a dog. If a dog whistle has a frequency of 3.0 x 10^4 Hz, what is the wavelength of the sound emitted?

What is a carrier wave and how does it affect what you hear on the radio

Ne way in which elements differ from each other is the structure of the electron cloud in each element's atoms. in an electron cloud, an electron that is farther away from the nucleus has

A55-kg pilot flies a jet trainer in a half vertical loop of 1200-m radius so that the speed of the trainer decreases at a constant rate. knowing that the plane has a speed of 550 km/h at point a, and the pilot experiences weightlessness at point c (i.e., the normal force from the seat bottom is zero), determine (a) the deceleration of the plane, (b) the force exerted on her by the seat of the trainer when the trainer is at point b.
