Marie Curie studied the radiation of all compounds containing the known radioactive elements, including uranium and thorium, which she later discovered was also radioactive. She also found out that:
- you can exactly measure the strength of the radiation from uranium;
- the intensity of the radiation is proportional to the amount of uranium or thorium in the compound - no matter what compound it is;
- the ability to emit radiation does not depend on the arrangement of the atoms in a molecule; it must be linked to the interior of the atom itself - a revolutionary discovery!
When she realized that some uranium and/or thorium compounds had stronger radiation than uranium, she made the following hypothesis: there must be an unknown element in the compound which had a stronger radiation than uranium or thorium. Her work aroused the interest of her husband, Pierre Curie, who stopped his own research on crystals and joined the "detective work" with his wife. And Marie was proven right: in 1898 the Curies discovered two new radioactive elements: radium (named after the Latin word for ray) and polonium (named after Marie's home country, Poland).
The role of slave resistance in bringing slavery to an end is often overlooked. However, slave revolts were very important as they put pressure on the colonial system and made politicians realise that ultimately slavery had to be abolished. A slave revolt was what all those involved in the slave trade feared most.
We would get B.
This happens because it's just another key detail, it's a detail that's aside of the sentence that may or may not be important.
Answer: women were important to the settlement house movement
Explanation:
It would be A. Even our architecture is influenced from them, even the romans liked it.
