Chadwick's experiment on the deflection of alpha particles by a thin sheet of beryllium led to the discovery of the neutron, as the neutral particle responsible for this deflection. Based on his results, Chadwick proposed that the atom had a neutral particle in its nucleus, now known as the neutron, which explained the missing mass in atoms. This led to the development of the neutron theory of the atomic nucleus.

What year did Alfred Wegener come up with Continental Drift?
Alfred Wegener proposed the theory of Continental Drift in 1912.
How did Ernest Rutherford come up with his discoveries?
Ernest Rutherford made his discoveries through his pioneering work in the field of nuclear physics. He conducted the famous gold foil experiment where he observed the scattering of alpha particles, leading him to propose the nuclear model of the atom. His experiments and observations paved the way for future breakthroughs in understanding the structure of the atom.
What date will Nibire come clostest to earth?
There is no scientific evidence to support the existence of Nibiru, also known as Planet X. It is a conspiracy theory and not recognized by the astronomical community. Therefore, we cannot provide a date for when it will come closest to Earth.
Where did gravity come from. What did Gravity come from. and When did Gravity come into being?
Of those three questions, the only one that makes any sense is the last one. Gravity doesn't come from a place (the "Where" part) or a thing (the "What" part). Gravity is strongly suspected to have come into existence at the time of the Big Bang, along with the other three fundamental forces. If the Theory of Everything people are right, at extremely high energies the forces combine; gravity would probably have been the first to separate out, at about one Planck time after the Big Bang (a "Planck time" is about 5 x 10-44 seconds).
Where did the theory of gravity come from?
Though astronomical observations and theories have been around for thousands of years, the coming together of knowledge that tied down the effects of gravity, is attributed to mainly newton and einstien, though a true explanation of gravity is still elusive.
What happens if a scientists observations do not match the scientific theory?
If observations don't match the theory, then either the theory or the experiment is wrong. Maybe a measuring device isn't sensitive or accurate enough. If the experiment is right, but results doesn't match theory, then it's time to come up with a new theoru that matches the experiment's results.
What is it called when you want the results of your experiment to come out a certain way?
When someone wants the results of an experiment to come out a certain way, it is called experimenter bias or confirmation bias. This can lead to skewed results and undermine the validity of the experiment.
What scientist performed an experiment with results that provided evidence that flies come from maggots concluding that the theory of spontaneous generation was NOT true for flies?
Francesco Redi was an Italian physician and naturalist who proved maggots come from flies. He was the first scientist to challenge the theory of spontaneous generation.
What is the control variable in the experiment is the?
The purpose of a control variable in an experiment is to allow the experiment to come out with accurate results. It makes it a lot easier to measure the results when different things aren't affecting it.
What is a scientific Theory and how is it different then a hypothesis or a scientific law?
A scientific theory is an experiment that still needs to be tested, but is believed to be true. A hypothesis is a fact and data based guess as to what the result(s) of an experiment will be. A scientific law is proven to be true and states that the results of the experiment will always be the same, and needs no further testing. An example of a scientific theory is the cell theory, which states that all living things are composed of at least one cell and that cells come from other cells.
Which part of the scientific method would come after the experiment?
After the experiment, the next step in the scientific method is to analyze the data collected from the experiment. This involves organizing and interpreting the results to draw conclusions about the hypothesis.
What did Redi prove in his experiment?
Redi's experiment proved that maggots do not spontaneously generate from decaying meat, but rather come from the eggs of flies. This refuted the prevailing theory of spontaneous generation.
Does the experiment come before data?
Yes. The order is question, hypothesis, lab, organize data, communicate results
What does data obtained mean?
Data obtained from an experiment is the results you got from whatever test or experiment you did. Data obtained for a research paper is the information you got from your research. Basically, it is the data/info/results/etc you need to come to a certain conclusion.
Why would ten scientists all conduct the same experiment?
The more scientists that conduct the same experiment, with the same results, the more the findings can be trusted. Also, more scientists are more likely to come up with variances or solutions due to different ways of thinking and approaching things.
Where does chadwick surname come from?
It's found in the early records of Staffordshire in England.
How long does it take a music theory exam reuslt to come in?
I did a music theory exam from the ABRSM theory exams in September and the results came out in around October & November so its around 1 to 2 months.
