A submarine on the surface of water sends out a wave pulse that reflects at the bottom of the ocean and returns back. The submarine detects the time between the transmission of the pulse and the arrival of the reflected pulse as 2.5 s and the depth of the ocean is 1875 m at that point. What is the speed with which the wave travels in water 1500 m/s

750 m/s

340 m/s

375 m/s

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.

In a given chemical reaction, the energy of the products is greater than the energy of the reactants. which statement is true for this reaction?

The temperature at a point (x, y) is t(x, y), measured in degrees celsius. a bug crawls so that its position after t seconds is given by x = 6 + t , y = 8 + 1 3 t, where x and y are measured in centimeters. the temperature function satisfies tx(3, 9) = 5 and ty(3, 9) = 4. how fast is the temperature rising on the bug's path after 3 seconds? (round your answer to two decimal places.)
