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?
You will need to add weight to the feather. That's like asking to demonstrate the that of a helium filled balloon and a bowling ball.
How can rate constant be determined from the rate law?
The rate constant is the reaction rate divided by the concentration terms.

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

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 car insurance companies calculate car insurance rate based on the drivers safety record?
Most car insurance companies base their premiums on the driver's safety record. This ensures the best possible rate for driver's who can demonstrate a safe driving history.
What is the probability rate of someone having the Charcot-Marie-Tooth disorder?
Approximately 125,000 people in the USA and 1in every 2,500 people world wide.

How do you reply to Rate your communication skills on a scale of 1 to 10 with 10 representing excellent communication skills. Give three 3 examples from your past work experiences that demonstrate the?
I would never rate myself below an 8. You should also give examples of how you have improved and what you are planning on doing in the future to continue improving.
