Marie curie and her husband pierre were henri becquerel's graduate students when becquerel
discovered spontaneous radiation. in 1903, the curies shared the nobel prize for physics with becquerel.
based on the discovery of radioactivity, which statement best describes becquerel's influence on
marie curie's work with radioactivity?
o
o
becquerel proposed the concept of radiation and marie curie reproduced his experiments.
becquerel's work proved that radiation was far too dangerous for anyone to experiment with.
marie curie's work with becquerel made her more curious and prompted her to research and
experiment with radioactivity.
marie curie was such a talented scientist that becquerel's work did not have any influence on her
discoveries.

The energy of a photon was found to be 3.38 × 10–19 j. planck’s constant is 6.63 × 10–34 j • s. which color of light corresponds to this photon?

Road users moving into your lane, brake lights, and abrupt changes in road surface are a. rare at night b. indicators of potential hazards c. not worth worrying about before you reach them d. no problem for experienced drivers

While studying chemical reactions and conservation of matter, sarah's class conducted a variety of experiments. sarah and her lab partner found the mass of a wax candle and placed the candle in a flask. the students lit the candle and let it burn to completion. all that was left was wax and charred candle wick. per their teacher's instructions, the students found the mass of the products. their data can be seen in the data table. formulate a hypothesis the students could test to explain why the experiment did not support the law of conservation of matter. a) the students could repeat the experiment using different candles; there might have been a flaw in the candle. b) the experiment should be repeatable. the students should run several trials and then take an average of the after mass in each trial. c) the students should have someone in the class check their measurement skills as they repeat the experiment. they may have made an error using the balance. d) the students should burn the candle in a container that has some type of lid so that any gas that is a product of the reaction can be contained and massed. submit
