Radiation. 1  Radiation is the emission of energy as waves or particles or rays. 2  Radiation does not require a medium to transfer energy. 3  Radiant energy is either reflected or absorbed by matter. 4  Energy that is absorbed increases the kinetic energy of the object. 5  This increases the temperature of the object.
The Pennsylvania Turnpike could also be considered one of the first Interstate Highways. On October 1, 1940, 162 miles (261 km) of the highway now designated Iâ70 and Iâ76 opened between Irwin and Carlisle. The Commonwealth of Pennsylvania refers to the turnpike as the Granddaddy of the Pikes.
The first such funding came under the Federal-Aid Highway Act of 1952, which authorized a token amount of $25 million a year for the Interstate System in Fiscal Years (FY) 1954 and 1955. The 1952 Act retained the standard matching ratio (Federal share: 50 percent). The Federal-Aid Highway Act of 1954 authorized $175 million a year for the Interstate System (FYs 1956 and 1957), with a Federal-State matching ratio of 60-40.
