Input: Read this: The light from LEDs can be modulated very quickly so they are used extensively in optical fiber and free space optics communications. This includes remote controls, such as for TVs, VCRs, and LED Computers, where infrared LEDs are often used. Opto-isolators use an LED combined with a photodiode or phototransistor to provide a signal path with electrical isolation between two circuits. This is especially useful in medical equipment where the signals from a low-voltage sensor circuit (usually battery-powered) in contact with a living organism must be electrically isolated from any possible electrical failure in a recording or monitoring device operating at potentially dangerous voltages. An optoisolator also allows information to be transferred between circuits not sharing a common ground potential.
Question: What is an example of a device that uses free space optic communications?

Output: remote controls

QUES: Sanskrit has greatly influenced the languages of India that grew from its vocabulary and grammatical base; for instance, Hindi is a "Sanskritised register" of the Khariboli dialect. All modern Indo-Aryan languages, as well as Munda and Dravidian languages, have borrowed many words either directly from Sanskrit (tatsama words), or indirectly via middle Indo-Aryan languages (tadbhava words). Words originating in Sanskrit are estimated at roughly fifty percent of the vocabulary of modern Indo-Aryan languages, as well as the literary forms of Malayalam and Kannada. Literary texts in Telugu are lexically Sanskrit or Sanskritised to an enormous extent, perhaps seventy percent or more.
What language has influenced the languages of India?

ANS: Sanskrit

Question: Yale's secret society buildings (some of which are called "tombs") were built both to be private yet unmistakable. A diversity of architectural styles is represented: Berzelius, Donn Barber in an austere cube with classical detailing (erected in 1908 or 1910); Book and Snake, Louis R.
