Tack of Pressure Sensitive Adhesives. Tack, or quick stick, is one of the most important properties of pressure sensitive adhesives (PSAs). The definition of tack is the property of a pressure sensitive adhesive that allows it to adhere to a surface under very slight pressure. It is determined by the ability of the adhesive to quickly wet the surface it contacts.
How far inland can a tsunami go? With wave speeds that can reach as much as 435 miles per hour, a tsunami can travel as far inland as 10 miles, depending on the slope and the shape of the shoreline that it is traveling across.
Tsunamis range in size from inches to over a hundred feet. In deep water (greater than 600 feet/180 meters), tsunamis are rarely over 3 feet (1 meter) and will not be noticed by ships due to their long period (time between crests). As tsunamis propagate into shallow water, the wave height can increase by over 10 times.Tsunami heights vary greatly along a coast. As a tsunami leaves the deep water of the open ocean and travels into the shallower water near the coast, it transforms.
