Why was existence of a tiny massive and positively charged nucleus was deduced from the observations?
Why or how? The number of alpha particles deflected was small ... indicating the nucleus was small. The deflection of an even smaller amount of alpha particles almost straight back toward the emitting source proved that the nucleus was heavier than the alpha particle. According to previous atomic theory, the alpha particles should have all gone straight through the metal foil, with none deflected.
Math calculations based on the deflection pattern showed that the nucleus was repelling the alpha particles, that they were not actually hitting and bouncing off the nucleus... this showed that the nucleus was positively charged.

How did astronomers deduced that star called 51 Pegasi has a planet revolving around it?
The star they were observing, 51 Pegasi, moved back and forth only very slightly. Therefore, they knew the invisible object could not have enough mass to be a star. They deduced that it must be a planet.
The molecular structure of DNA was deduced?
The molecular structure of DNA was deduced by James Watson and Francis Crick in 1953. They proposed the double helix structure based on X-ray diffraction data collected by Rosalind Franklin and Maurice Wilkins, along with their own model building efforts. This discovery revolutionized our understanding of genetics and laid the foundation for further research in molecular biology.
Can Newton's second law be deduced from the third law?
No, it's the other way around. Newton's third (also first) law can be mathematically derived from his second law.
Where do you find that the earth is spherical?
The Earth isn't actually perfectly spherical. It is slightly flattened at the poles. To find evidence of Earth's round shape, pictures taken from space are good secondary data to provide evidence.
What keeps particles in a nucleus together?
This is called the strong nuclear force, at close range it overcomes electrostatic repulsion between protons. This force had to be deduced from the stability of nuclei, but theoretical physicists are still trying to explain what it really is and how it works.
What is a sentence for astutely?
Sherlock Holmes was known for solving cases by astute observations.
What experiment did j.j Thomson do?
J.J. Thomson is best known for his experiment with cathode rays, where he deduced the existence of negatively charged particles (electrons) in atoms. By measuring the deflection of these rays in a magnetic field, Thomson was able to determine the charge-to-mass ratio of the electron.
How do experiments help scientists learn abut the world?
Experiments helps scientist test the ideas. Experiment is simply an act of performing a controlled test about an idea. Before an experiment is made, observations using senses must be deduced from the environment at first. Observations leads to the formulation of hypothesis.
What is is an answer deduced from the analysis of data?
Conclusion
What is another word for deduced?
Analyzed.
What is the meaning of inferential?
Deduced or deducible by inference.
What is the deductible?
A statement or a conclusion that has been deduced.
What does deduced mean in kids definition?
"Deduced" is just a fancy way of saying "figured out."
What is the deductive structure?
A statement or a conclusion that has been deduced.
What cannot be deduced from a strategic-group map?
yes
Which scientist deduced the size of the atomic nucleus?
Rutherford
What is the past tense of deduce?
The past tense of deduce is deduced.
