A scientist is studying how large tsunamis form. The scientist uses the following model to examine the properties of large tsunamis. They know that tsunamis, or ocean waves with a very large wave amplitude, happen after another event, such as an earthquake or landslide has dramatically shifted the earth’s crust and therefore the water above that crust. While it is difficult to see the amplitude and wavelength of the individual waves while they are far out at sea, we can see how large they are as they get into shallower areas as they approach the shoreline. Based on the model and explanation, how does an earthquake cause tsunamis? A. An earthquake’s seismic wave provides mechanical energy to the ocean. As energy is added the amplitude of the wave is increased. B. As the earthquake vibrates more waves are created. More waves means that there is less space between them decreasing the wavelength. Because amplitude is inversely related to wavelength, this means that the waves must be less energetic. C. As the earthquake creates more waves the frequency is increased. Because amplitude is directly related to frequency, the amplitude is also increased. D. An earthquake’s seismic waves overlap and build upon each other as the earth continues to shake. As the earth shakes more, the amplitude of the wave increases.

At 20∘c, the hole in an aluminum ring is 2.800 cm in diameter. you need to slip this ring over a steel shaft that has a room-temperature diameter of 2.804 cm . 1. to what common temperature should the ring and the shaft be heated so that the ring will just fit onto the shaft? coefficients of linear thermal expansion of steel and aluminum are 12×10−6 k−1 and23×10−6 k−1 respectively.
