How did Marie curie demonstrate generosity?
Marie Curie demonstrated generosity by freely sharing her scientific discoveries and knowledge with others. She refused to patent the technique for isolating radium, wanting it to benefit humanity instead of seeking personal gain. Additionally, she dedicated her Nobel Prize winnings to support further research in her field.
Is radiation measured in emissions sec called the curie?
No, radiation is not measured in emissions per second. The curie (Ci) is a unit used to measure the activity of a radioactive substance, representing the rate of radioactive decay. The unit for measuring radiation exposure is the sievert (Sv).
What is a curie and becquerel?
Curie (Ci) and Becquerel (Bq) are both units in which activity is measured; activity being the time rate of change of the number of the radioactive nuclei.Becquerel is the common/most widely used unit.Curie is the SI unit.1 Ci = 3.7 x 1010 Bq
What did Marie Curie discover?
Marie Curie is famous for discovering the element Radium, previously unknown. The history of this is an interesting progression, like so much in science. The physicist Roentgen discovered X-rays, and found that they would pass through solid matter, and also that they would affect photographic plates. The scientist Becquerel discovered that a mineral called pitchblende would affect these plates even through their wrappers, and suspected that the mineral was producing X-rays. This was puzzling, because Roentgen made X-rays using high voltages in a vacuum chamber, while pitchblende just sat there but somehow did the trick. Curie thought that there must be something unknown in pitchblende. She bought tons of it, and started trying to isolate something else from it. Eventually she managed to get a few grams of something from the tons of original stuff. This new substance had remarkable properties. It was always warmer than its surroundings; it shone in the dark, and it produced something very like X-rays. The rate at which these three things were produced did not seem to diminish with time. She had produced a radioactive substance with a long half-life. Because it radiated light, heat and X-rays it became called Radium.
How could you carry out a demonstration on Earth of a feather falling at the same rate of a bowling ball?
To demonstrate a feather falling at the same rate as a bowling ball on Earth, you can create a vacuum chamber to remove air resistance. When both the feather and the bowling ball are dropped in the vacuum, they will fall at the same rate due to the absence of air drag affecting their descent, as demonstrated by Galileo's famous experiment on falling bodies.

What is the graduation rate for curie high school?
Curie High School earn an 78% graduation percentage which it is a very good percentage rate overall. It is a great school where its mission is to prepare al students through multi-based curriculum and prepare them for success and for college and career as well.
How do you calculate the dose rate from an Am-Be neutron source?
neutrons are produced at a rate of 2.8x10+6 neutrons/second/curie Am-241 for an optimally, well mixed source of americium and beryllium. the neutron dose rate of a one curie Am-Be source would be 34.7 mR/hr (or 347 µSv/hr) at 30 cm. the gamma dose rate of a one curie Am-Be source would be 0.17 mR/hr (or 17 µSv/hr) at 30 cm. americium-241 also decays by spontaneous fission with a half life of 2x10+14 years, producing 0.18 neutrons/second/curie Am-241. note that beryllium is not required for this neutron production mechanism.

What is the life expectancy of a person with Wolf-Hirschhorn Syndrome?
life expectancy is shortened but recent research demonstrate that mortality rate is less than reported in the past and that mortality rate correlates with the size of the deletion
Which mammals has the highest rate of homosexuality?
Bonobo Apes have the highest. The entire population appears to be 100% bisexual.
What are some example problems that demonstrate the application of Fick's Law?
Some example problems that demonstrate the application of Fick's Law include calculating the rate of diffusion of a gas through a membrane, determining the concentration gradient of a solute in a solution, and predicting the movement of molecules in a biological system.
How do you demonstrate an equilibrium wage rate?
It's the point of intersection between: Demand for labour And Supply for labour The 2 axis in which it's living in is: (Y) axis (vertical) : average wage rate (X) axis (horizontal): amount of workers
What is a great example of a wave that tuning forks demonstrate?
One great example of a wave that tuning forks demonstrate is a sound wave. When a tuning fork is struck, it vibrates and produces sound waves that travel through the air. The frequency of the sound wave is determined by the rate of vibration of the tuning fork.
