The tower provides a broadcast area of roughly 9,700square miles. Five miles away stands the KRDK-TV mast, which at 2,060 feet is currently the fifth-tallest structure in the world. A: Express the relation for the potential energy lost by the body. Television- and radio-transmitting towers are among the tallest and most fragile structures built, with some up to 2,000 ft. (609.60 m) in height. The vertical height of the climb is 1,120 m, and the combined mass of the rider and bicycle is 85 kg. Work began on replacement of the full-height mast with a more durably-built structure on April 1, 1998, and had reached the towers previous height by July 30. Its broadcast area is roughly 30,000 square miles thats an area about the size of Hawaii, the District of Columbia, Massachusetts, New Jersey, and Connecticut put together, with a thousand square miles left over. It contains two million feet of steel, guy wire strands and elevator cable, and the structure, along with its guy anchors, takes up 160 acres of space. Euclid, Minnesota, at what looks to all appearances to be a large If a hunter at the base of the tower shot a .45 caliber pistol at a goose flying near the top, he would have to lead the goose by more than the length of a football field.
