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 paved road in the United States was the former Philadelphia and Lancaster Turnpike, which makes up part of the present-day U.S. Route 30. Opened in 1795, the Turnpike connected the cities of Lancaster and Philadelphia, and was designed by a Scottish engineer named John Loudon McAdam.
