What are alpha particles used for?
We commonly see an isotope of americium generating alpha particles to ionize air in smoke detectors. A source generates alpha particles to ionize air in industrial settings so that the ionized air will quickly and effectively dissipate static charges. A radio pharmaceutical generates alpha particles, and the unsealed source irradiates tumors in patients that are so implanted. We find alpha particle sources in the physics lab where they are used in experiments and demonstrations. Alpha particles can be accelerated for use as "atomic bullets" in high energy physics research.
What year did James Rutherford invent the atomic bomb?
never, but Leo Szilard who was working at Rutherford's lab at the time invented the atomic bomb in 1933.
What actors and actresses appeared in Source Sound Lab - 2000?
The cast of Source Sound Lab - 2000 includes: Ray J Tracey McCall as Dancer (2001)
Do you agree or disagree with your lab partner who says a battery provides not a source of constant current but a source of constant voltage?
agree
In the Doppler effect lab what best describes what you demonstrated about speed and pitch?
In the Doppler effect lab, we demonstrated that the speed of a sound source affects the pitch perceived by an observer. As the source moves towards the observer, the frequency (pitch) increases, and as the source moves away, the frequency decreases. This change in frequency is due to the compression and rarefaction of sound waves as the source moves relative to the observer.
Who said atoms contain mostly empty space?
Anybody who knows much about atoms and is willing to ignore virtual particles. The credit for actually discovering this should probably go to Rutherford. (Or Rutherford, Geiger, and Marsden ... Geiger and Marsden actually did the experiment in Rutherford's lab, and Rutherford was the one who explained the results.)
How did Louis Pasteur discover the source of the plague?
He was a pioneer in microbiology. He in his lab discovered Yersinia pestis bacterium.
What is Alpha in Mega Man Battle Network 3?
Alpha is the final boss of the game, located at the WWW base. It is the "Alpha" version of the internet, before the bugs could be worked out of it. The bugs coalesced to give Alpha a basic level of intelligence and instinct, and after a brief flare up of problems leading to the supposed execution of Bass, it took over all devices linked to it, leading to the six-month long Alpha Rebellion (or Revolt). When this was over, Alpha's creator installed Guardian in its core and sealed it away in Sci-Lab behind the Tetragates. It is essentially omnipotent and will eventually destroy the world.
What is the best way to make rock candy in a classroom science lab?
EAPrep is the leading source of information on Texas foundations and nonprofits. You can making Rock Candy in the Science Lab and Music in the Classroom at EAPrep.
In the Doppler effect lab what statement best describes what you demonstrated about speed and pitch?
In the Doppler effect lab, we demonstrated that the perceived pitch of a sound changes depending on the motion of the source and observer. As the source moves towards the observer, the pitch increases, while as the source moves away, the pitch decreases. This change in pitch is due to the compression or expansion of the sound waves as they travel through the medium.
Why do you always use voltage source in lab not current source?
Current is created by voltage (potential difference), not the other way round. It's the voltage - or 'push' - that is making your current move.
Why does my female Lab wait until my male Lab eats his chew before she eats hers?
I don't like to apply pack hierarchy to dogs as it's overdone and often incorrect, but perhaps because she views him as the alpha? Wolves will wait to eat until the pack leader is done? Dunno.
