Sewing machine stitches made by bartacking sewing machine like janome is actually a lockstitch sewing machine group which produced a very high density sewing machine stitches in a very short length for increase strength of that particular place. Bartacking machine contains one needle and one bobbin.
That tsunami didn't travel far inshore, but others did. Ted argues that a tsunami that hit the Shoalhaven delta near Nowra, between 5000 and 4000 years ago, ran 10 km inland, while deposits near the Blue Mountains hint that another tsunami ran over cliffs more than 60 m high, and then rushed inland. A similar event today would have the potential for widespread destruction.
An earthquake on the ocean floor in the Gulf of Alaska produces a tsunami (sometimes incorrectly called a tidal wave) that reaches Hilo, Hawaii, 4,450 km away, in a time interval of 9 h 30 min. Tsunamis have enormous wavelengths (100 to 200 km), and the propagation speed for these waves is shown below ,... show more An earthquake on the ocean floor in the Gulf of Alaska produces a tsunami (sometimes incorrectly called a tidal wave) that reaches Hilo, Hawaii, 4,450 km away, in a time interval of 9 h 30 min.

From the information given, find the average wave speed and the average ocean depth between Alaska and Hawaii.
