What do you think would be the observation if the α-particle scattering experiment is carried out using a foil of a metal other than gold?
If the α-scattering experiment is carried out using a foil of a metal rather than gold, there would be no change in the observation. In the α-scattering experiment, a gold...

Enlist the conclusions drawn by Rutherford from his α-ray scattering experiment.
Rutherford concluded from the α-particle scattering experiment that– (i) Most of the space inside the atom is empty because most of the α-particles passed through the gold foil without getting deflected. (ii)...

Suppose you are given a chance to repeat the alpha-particle scattering experiment using a thin sheet of solid
In the alpha-particle scattering experiment, if a thin sheet of solid hydrogen is used in place of a gold foil, then the scattering angle would not be large enough. This...

Excessive and continuous use of pesticides has resulted in evolution of some new species of pests.
Excessive use of pesticides has resulted in selection of resistant varieties in a much lesser time scale, as evolution is a stochastic process based on chance events in nature and...
