Indicate the conclusions drawn by Rutherford from his `alpha`-particle scattering experiment.

Statement I: The total positive charge and almost all the mass of an atom are confined in the nucleus. Statement II: In Rutherford's alpha -particle scattering experiment, majority of the alpha -particles penetrate the target without any deflection.

What is the advantage of using gold rather than other metals in Rutherford's alpha particle scattering experiment ?

What is Rutherford’s alpha - ray scattering experiment? What are its conclusions

Show the result of hybridization till F2 generation between a pure black (BB) coarse haired (RR) guinea-pig and a pure white (bb) smotth haired (rr) . Guinae-pig by a cheaker board. State the conclusion one can reach from this hybridization experiment.

Indicate the conditions under which the ratio of de Broglie wavelengths of an alpha -particle and a proton will be-

In the Rutherford’s experiment of alpha particles scattering on thin gold foil, in 1911, it was found that only ion alpha -particle among, 20,000 was deflected through 180^@ . This was due to

Determine what conclusions can be drawn from the Miller and Urey’s experiment?

In an experiment done by Griffith it was found that when virulent capsulated smooth 'S' bacteria were injected into healthy mice, the mice dies of pneunomia. When mice were injected with non virulent 'R' forms of same bacteria, they survived and did not die to pneumonia. in another case when S-forms were killed by heating at above 60^(@)C and injected, rats did not get pneumonia, but when killed, s-forms and R-forms of bacteria were mixed and injected, the rats suffered from pneumonia and died. which one of the following conclusions can be drawn from the above experiment?

In the Rutherford scattering experiment the number of alpha particles scattered at an angle theta=60^@ is 12 per min.The number of alpha particles per min when scattered at angle of 90^@
