Infrared tracking, also known as infrared homing, refers to a passive missile guidance system, which uses the emission from a target of electromagnetic radiation in the infrared part of the spectrum to track it. Missiles that use infrared seeking are often referred to as "heat-seekers", since infrared (IR) is just below the visible spectrum of light in frequency and is radiated strongly by hot bodies. Many objects such as people, vehicle engines, and aircraft generate and retain heat, and as such, are especially visible in the infrared wavelengths of light compared to objects in the background.
Along with aircraft and people, what objects notably create and retain heat?
A: vehicle engines

Johnson, Jimmy Carter, Bill Clinton) usually fare better than their Northern counterparts do in Tennessee, especially among split-ticket voters outside the metropolitan areas.
Democratic presidential candidates from which region's states have fared best in recent Tennessee history?

In 1945, the British entrepreneur J. Arthur Rank, hoping to expand his American presence, bought into a four-way merger with Universal, the independent company International Pictures, and producer Kenneth Young. The new combine, United World Pictures, was a failure and was dissolved within one year. Rank and International remained interested in Universal, however, culminating in the studio's reorganization as Universal-International. William Goetz, a founder of International, was made head of production at the renamed Universal-International Pictures Inc., which also served as an import-export subsidiary, and copyright holder for the production arm's films. Goetz, a son-in-law of Louis B. Mayer decided to bring "prestige" to the new company. He stopped the studio's low-budget production of B movies, serials and curtailed Universal's horror and "Arabian Nights" cycles. Distribution and copyright control remained under the name of Universal Pictures Company Inc.
Who was the head of production at Universal-International Pictures?
A:
William Goetz
