How did Becquerel discovered radioactivity discovered radioactivity?
he noticed the first effects of radioactivity while he observed that with exposure to the sunlight the mineral gave off a penetrating energy that could expose film.
What observation caused Becquerel to pose another question?
he
What observation caused Henri Becquerel to pose another question?
he
Which statement is an obervation if the ramp is steeper then the ball will roll faster or friction slowed the ball down or gravity caused the ball's motion?
"If the ramp is steeper than the ball will roll faster" can be observed during experiments. "Friction slowed the ball down" and "Gravity caused the ball's motion" are both conjectures (guesses).

How would you describe bequerel's experiments?
Henry Becquerel radioactivity experiment is an example of finding some thing out of surprise without looking for it. The actual experiment is mentioned on the wikipedia page of Henry Becquerel. Once in my Nuclear Engineering class my teacher told that Henry placed his personal belongings into a drawer along with a salt piece of Uranium and photographic plates. The plates got fogged. Henry was curious to know what caused the fogging of the plates. He experimented by placing the things that were present in the drawer earlier one by one along with a photo graphic plate and recorded the results. Well the realted link will take you to a video on the experiment conducted by Henry Becquerel.

What is the photographic term for the twinkle in their subject's eye caused by a reflection?
Catchlight.
When scientist discovered radioactivity?
Radioactivity was discovered during 1896 by Henri Becquerel, who was a French scientist when he was working on phosphorescent materials. Other research was done by Becquerel, Ernest Rutherford, Paul Villard, Pierre Curie, Marie Curie, and others afterwards.
What is the definition of texture in interior or photographic design?
Texture is a term with which many interior or photographic designers are familiar. By definition, texture is "the properties held and sensations caused by the external surface of objects received through the sense of touch."
How did Antoine Becquerel improve the atomic theory?
=Becquerel's earliest work was concerned with the plane polarization of light, with the phenomenon of phosphorescence and with the absorption of light by crystals (his doctorate thesis). He also worked on the subject of terrestrial magnetism. In 1896, his previous work was overshadowed by his discovery of the phenomenon of natural radioactivity. Following a discussion with Henri Poincaré on the radiation which had recently been discovered by Röntgen (X-rays) and which was accompanied by a type of phosphorescence in the vacuum tube, Becquerel decided to investigate whether there was any connection between X-rays and naturally occurring phosphorescence. He had inherited from his father a supply of uranium salts, which phosphoresce on exposure to light. When the salts were placed near to a photographic plate covered with opaque paper, the plate was discovered to be fogged. The phenomenon was found to be common to all the uranium salts studied and was concluded to be a property of the uranium atom. Later, Becquerel showed that the rays emitted by uranium, which for a long time were named after their discoverer, caused gases to ionize and that they differed from X-rays in that they could be deflected by electric or magnetic fields. For his discovery of spontaneous radioactivity Becquerel was awarded half of the Nobel Prize for Physics in 1903, the other half being given to Pierre and Marie Curie for their study of the Becquerel radiation
Is irritation in eyes is caused by the PAN pollutant?
Yes, irritation in eyes, which is observed in periods of strong photosmog, is caused by Peroxyacetyl Nitrate (PAN).
What causes the most readily observed east-to-west motion of the objects in the night sky caused by?
This illusion is caused by the west-to-east rotation of the earth.
What side effects are caused by ademetionine?
The only side effects observed with SAMe in clinical trials were mild gastrointestinal distress.
