RUTHERFORD'S ATOMIC MODEL:-
Rutherford proposed that all the positive charge and mass of the atom was concentrated in a small central region which is called the nucleus.This model failed to explain the stability of an atom.
Splitting of signals is caused by: (1) Proton (2) Neutron (3) Positron (4) Electron Ans: (1) Proton
Q. A beam of electrons travelling with a speed of 4 X 10 7 ms -1 is projected normal to a magnetic field of B = 10 -3 Wb m -2 . What is the path of the beam in the magnetic fiel
V-I Characteristics of Constant Current Source A source which has high internal resistance (or impedance) as compared to load resistance (or impedance) i
Q. An electron beam is accelerated through a potential difference of 104 volt. Find the de Broglie wavelength. λ = 12.27 A o / √V λ = 12.27 A o / √10 4 = 0.1227
A PROJECT REPORT ON A MODEL
Illustrate briefly the significance of entropy? Determine the work done when 2 mole of an ideal gas expands isothermally and reversible from 10 atm. To 2 atm. Pressure at 27 0 C
Echo vs. Reverberation Sound is a mechanical wave that travels by a medium from a single location to other. This motion by a medium occurs as one particle of the medium interac
Lyman series: The series which define the emission spectrum of hydrogen while electrons are jumping to the ground state. All lines are in the ultraviolet.
Out of ordinary and extra-ordinary waves, which wave obeys Snell's law?
Consider air (ideal gas) as working substance inside a piston-cylinder device (closed system). This air undergoes a power cycle as shown in figure. Determine work output per unit m
