Air pressure decreases at a rate of 1.5 (pascals) per kilometer in the eastward direction. in addition, the air pressure is decreasing at a constant rate with respect to time everywhere. a ship sailing eastward at 10 km/hour past an island takes barometer readings and records a pressure drop of 60 in 2 hours. estimate the time rate of change of air pressure on the island. (pascal is a unit of air pressure =/m2=/m∗)

True or false when elements combine to form a mixture, the resulting chemical properties may be very different from those of the elements that make it.

Afisherman notices that his boat is moving up and down periodically without any horizontal motion, owing to waves on the surface of the water. it takes a time of 2.20 s for the boat to travel from its highest point to its lowest, a total distance of 0.670 m . the fisherman sees that the wave crests are spaced a horizontal distance of 5.80 m apart. (a) how much is the wavelength? (b) find the period of the wave. (c) how fast are the waves traveling? (d) what is the amplitude a of each wave?
