Context and question: The concept of emissivity is important in understanding the infrared emissions of objects. This is a property of a surface that describes how its thermal emissions deviate from the ideal of a black body. To further explain, two objects at the same physical temperature will not show the same infrared image if they have differing emissivity. For example, for any pre-set emissivity value, objects with higher emissivity will appear hotter, and those with a lower emissivity will appear cooler. For that reason, incorrect selection of emissivity will give inaccurate results when using infrared cameras and pyrometers.
What property describes how a surfaces thermal emissions give inaccurate results when using infrared cameras and pyrometers?
Answer: unanswerable
Context and question: One of the most significant impacts To Kill a Mockingbird has had is Atticus Finch's model of integrity for the legal profession. As scholar Alice Petry explains, "Atticus has become something of a folk hero in legal circles and is treated almost as if he were an actual person." Morris Dees of the Southern Poverty Law Center cites Atticus Finch as the reason he became a lawyer, and Richard Matsch, the federal judge who presided over the Timothy McVeigh trial, counts Atticus as a major judicial influence. One law professor at the University of Notre Dame stated that the most influential textbook he taught from was To Kill a Mockingbird, and an article in the Michigan Law Review claims, "No real-life lawyer has done more for the self-image or public perception of the legal profession," before questioning whether, "Atticus Finch is a paragon of honor or an especially slick hired gun".
Atticus Finch is a model of what for legal professionals?
Answer: integrity
Context and question: Isolated remains of Homo erectus in Hathnora in the Narmada Valley in central India indicate that India might have been inhabited since at least the Middle Pleistocene era, somewhere between 500,000 and 200,000 years ago. Tools crafted by proto-humans that have been dated back two million years have been discovered in the northwestern part of the subcontinent. The ancient history of the region includes some of South Asia's oldest settlements and some of its major civilisations. The earliest archaeological site in the subcontinent is the palaeolithic hominid site in the Soan River valley. Soanian sites are found in the Sivalik region across what are now India, Pakistan, and Nepal.
What type of resident lived at the site in Soan River Valley?
Answer:
palaeolithic hominid
