Question: Upon exposure, the amount of light energy that reaches the film determines the effect upon the emulsion. If the brightness of the light is multiplied by a factor and the exposure of the film decreased by the same factor by varying the camera's shutter speed and aperture, so that the energy received is the same, the film will be developed to the same density. This rule is called reciprocity. The systems for determining the sensitivity for an emulsion are possible because reciprocity holds. In practice, reciprocity works reasonably well for normal photographic films for the range of exposures between 1/1000 second to 1/2 second. However, this relationship breaks down outside these limits, a phenomenon known as reciprocity failure.
Try to answer this question if possible: How is the exposure of film changed?
Answer: by varying the camera's shutter speed and aperture
Question: The trip to the Moon took just over three days. After achieving orbit, Armstrong and Aldrin transferred into the Lunar Module, named Eagle, and after a landing gear inspection by Collins remaining in the Command/Service Module Columbia, began their descent. After overcoming several computer overload alarms caused by an antenna switch left in the wrong position, and a slight downrange error, Armstrong took over manual flight control at about 180 meters (590 ft), and guided the Lunar Module to a safe landing spot at 20:18:04 UTC, July 20, 1969 (3:17:04 pm CDT). The first humans on the Moon would wait another six hours before they ventured out of their craft. At 02:56 UTC, July 21 (9:56 pm CDT July 20), Armstrong became the first human to set foot on the Moon.
Try to answer this question if possible: The Lunar Module of the Apollo 11 was named after what animal?
Answer: Eagle
Question: The infrared portion of the spectrum has several useful benefits for astronomers. Cold, dark molecular clouds of gas and dust in our galaxy will glow with radiated heat as they are irradiated by imbedded stars. Infrared can also be used to detect protostars before they begin to emit visible light. Stars emit a smaller portion of their energy in the infrared spectrum, so nearby cool objects such as planets can be more readily detected. (In the visible light spectrum, the glare from the star will drown out the reflected light from a planet.)
Try to answer this question if possible: What do stars emit a smaller portion of in our galaxy?
Answer: unanswerable
Question: Initial reactions to the novel were varied. The New Yorker declared it "skilled, unpretentious, and totally ingenious", and The Atlantic Monthly's reviewer rated it as "pleasant, undemanding reading", but found the narrative voice"a six-year-old girl with the prose style of a well-educated adult"to be implausible. Time magazine's 1960 review of the book states that it "teaches the reader an astonishing number of useful truths about little girls and about Southern life" and calls Scout Finch "the most appealing child since Carson McCullers' Frankie got left behind at the wedding". The Chicago Sunday Tribune noted the even-handed approach to the narration of the novel's events, writing: "This is in no way a sociological novel. It underlines no cause ... To Kill a Mockingbird is a novel of strong contemporary national significance."
Try to answer this question if possible: What newspaper wrote that the novel has strong contemporary national significance?
Answer:
The Chicago Sunday Tribune
