Article: Energy transfer can be considered for the special case of systems which are closed to transfers of matter. The portion of the energy which is transferred by conservative forces over a distance is measured as the work the source system does on the receiving system. The portion of the energy which does not do work during the transfer is called heat.[note 4] Energy can be transferred between systems in a variety of ways. Examples include the transmission of electromagnetic energy via photons, physical collisions which transfer kinetic energy,[note 5] and the conductive transfer of thermal energy.

Question: Give one example of how energy can be transferred between systems?
Ans: transmission of electromagnetic energy via photons

Article: Lighthouse Point Park, a public beach run by the city, was a popular tourist destination during the Roaring Twenties, attracting luminaries of the period such as Babe Ruth and Ty Cobb. The park remains popular among New Haveners, and is home to the Five Mile Point Lighthouse, constructed in 1847, and the Lighthouse Point Carousel, constructed in 1916. Five Mile Point Light was decommissioned in 1877 following the construction of Southwest Ledge Light at the entrance of the harbor, which remains in service to this day. Both of the lighthouses and the carousel are listed on the National Register of Historic Places.

Question: After 1877 another lighthouse was build to replace File Mile Point, what was its' name?
Ans:
Southwest Ledge Light
