Question: Prior to Einstein's paper, electromagnetic radiation such as visible light was considered to behave as a wave: hence the use of the terms "frequency" and "wavelength" to characterise different types of radiation. The energy transferred by a wave in a given time is called its intensity. The light from a theatre spotlight is more intense than the light from a domestic lightbulb; that is to say that the spotlight gives out more energy per unit time and per unit space(and hence consumes more electricity) than the ordinary bulb, even though the colour of the light might be very similar. Other waves, such as sound or the waves crashing against a seafront, also have their own intensity. However, the energy account of the photoelectric effect didn't seem to agree with the wave description of light.
Try to answer this question if possible: What other types of wave besides light doesn't have its own intensity?
Answer: unanswerable
Question: Hundreds of movies have been shot or set in part within the city of Santa Monica. One of the oldest exterior shots in Santa Monica is Buster Keaton's Spite Marriage (1929) which shows much of 2nd Street. The comedy It's a Mad, Mad, Mad, Mad World (1963) included several scenes shot in Santa Monica, including those along the California Incline, which led to the movie's treasure spot, "The Big W". The Sylvester Stallone film Rocky III (1982) shows Rocky Balboa and Apollo Creed training to fight Clubber Lang by running on the Santa Monica Beach, and Stallone's Demolition Man (1993) includes Santa Monica settings. Henry Jaglom's indie Someone to Love (1987), the last film in which Orson Welles appeared, takes place in Santa Monica's venerable Mayfair Theatre. Heathers (1989) used Santa Monica's John Adams Middle School for many exterior shots. The Truth About Cats & Dogs (1996) is set entirely in Santa Monica, particularly the Palisades Park area, and features a radio station that resembles KCRW at Santa Monica College. 17 Again (2009) was shot at Samohi. Other films that show significant exterior shots of Santa Monica include Fletch (1985), Species (1995), Get Shorty (1995), and Ocean's Eleven (2001). Richard Rossi's biopic Aimee Semple McPherson opens and closes at the beach in Santa Monica. Iron Man features the Santa Monica pier and surrounding communities as Tony Stark tests his experimental flight suit.

Question: The rapid expansion of the Rus' to the south led to conflict and volatile relationships with the Khazars and other neighbors on the Pontic steppe. The Khazars dominated the Black Sea steppe during the 8th century, trading and frequently allying with the Byzantine Empire against Persians and Arabs. In the late 8th century, the collapse of the Göktürk Khaganate led the Magyars and the Pechenegs, Ugric and Turkic peoples from Central Asia, to migrate west into the steppe region, leading to military conflict, disruption of trade, and instability within the Khazar Khaganate. The Rus' and Slavs had earlier allied with the Khazars against Arab raids on the Caucasus, but they increasingly worked against them to secure control of the trade routes.
Try to answer this question if possible: Who were common enimies to both the Khazars and Byzantine Empire?
Answer: Persians and Arabs
Question: In the 2010s, American jurisdictions have experienced a shortage of lethal injection drugs, due to anti-death penalty advocacy and low production volume. Hospira, the only U.S. manufacturer of sodium thiopental, stopped making the drug in 2011. The European Union has outlawed the export of any product that could be used in an execution; this has prevented executioners from using EU-manufactured anesthetics like propofol which are needed for general medical purposes. Another alternative, pentobarbital, is also only manufactured in the European Union, which has caused the Danish producer to restrict distribution to U.S. government customers.
Try to answer this question if possible:  Up until 2015, who manufactured sodium thiopental?
Answer:
unanswerable
