What did john rutherford discover?
he is involved with science
Answers:
In 1908 Rutherford was awarded the Nobel Prize - for chemistry! The award citation read: "for his investigations into the disintegration of the elements, and the chemistry of radioactive substances." While at McGill University, he had discovered that the radioactive element thorium emitted a gas which was itself radioactive, but if the gas radioactivity was monitored separately from the thorium's, he found it decreased geometrically, losing approximately half its current strength for each minute that passed. The gas he had found was a short-lived isotope of radon, and this was the first determination of a "half-life" for a radioactive material.
I don't find John Rutherford, but here is Wikipedia's list of Rutherfords

Ernest (?) Rutherford split the atom
That his fathers name was Rutherford!
Other than that, haven't got a clue.
Sorry.
Didn't Rutherford do the experiement where he bombarded material with radiation (beta rays, if memory serves) and observed the motion of them. He found that a lot of the rays paths were largely unaffected and thus conjectured that atoms were mostly "empty", i.e, a nucleus with electrons in orbit.
I'm not 100% sure on that, haven't heard the name since A Level Physics.
did as physics last yr rutheford discoverd how particles were deflected using a gas chamber. use carbon dioxide gas and bounce beta particles to a gold leaf and watch them deflect.
rutherford discoverd that particles got deflected when they got near another particle.
he vacumm pumped a chamber then fired alpha gamma or beta - cant remember towards the gold leaf and noticed that every 1 in 8000 were deflected.
am not completly sure.. hope this will ring bells in someones head
where does the moon go when we can't see it in the sky at night?
how, many years do we have to WAIT before we can travel at the speed of light?
in textiles what is standard moisture regain?
dose anyone know how to combat fatigue.i have sytemic lupusand i have try things from the chemist.did not work
After watching a documentry..The Moon Landings..Real or the biggest hoax of all time?
If the earth is spinning why when viewed from space does it appear to stand still?
What is the base unit equivalent of the derived unit for gravitational field strength please?
Can you explain to me how I would factorise 15a^2 - 14a - 8.?
