Tack of Pressure Sensitive Adhesives. Tack, or quick stick, is one of the most important properties of pressure sensitive adhesives (PSAs).

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 may also be caused by underwater landslides or volcanic eruptions. They may even be launched, as they frequently were in Earthâs ancient past, by the impact of a large meteorite plunging into an ocean. Tsunamis race across the sea at up to 500 miles (805 kilometers) an hourâabout as fast as a jet airplane.At that pace they can cross the entire expanse of the Pacific Ocean in less than a day.sunamis race across the sea at up to 500 miles (805 kilometers) an hourâabout as fast as a jet airplane.
