Arock has vp=3.0 km/s and vs=1.5 km/s. (1) if a p wave traveling through the rock meets the surface at angle of 30°, determine the reflected p and s waves and the angles of reflections. (2) if an s wave traveling through the rock meets the surface at an angle of 60°, determine the reflected waves and the angles of reflections. show your steps to get the answers and sketch a figure showing all waves for case 1 and 2, respectively.

Why there is no inductive reactance in dc circuits

Tafari worked one summer on a ship that set weather buoys in the ocean. he watched how one of the buoys moved in the water. describe which parts of the wave would cause the buoy to bob up and down. which wave property determined how fast the buoys bobbed in the water? he observed that when the wind blew harder, the ocean waves were larger, and the buoys moved away from the ship. what effect, if any, did the waves have on how far the buoys moved? explain your answer.

The graph represents the distance a car travels over time while on the highway. which statement about the car's trip is accurate? a) the car does not move over time. b) the car travels at a constant velocity. c) the car's velocity increases constantly over time. d) the car's velocity decreases constantly over time.
