The accuracy in the measurement of speed of light is 3.00 xx 10^(8)m//s is

The radius of the first electron orbit of a hydrogen atom is 5.3 xx 10^(-11)m . What is the radius of the second orbit ?

The coefficient of viscosity eta of a gas depends on mass of the gas molecule, its effective diameter and its average speed. It is known that diameter of helium atom is 2.1xx10^(-10) m and its coefficient of viscosity, at room temperature is 2.0 xx 10^(-5) kg m^(-1)s^(-1) . Estimate the effective diameter of CO_(2) molecule if it is known that eta at room temperature for CO_(2) is 1.5 xx 10^(-5) kg m^(-1)s^(-1) .

The maximum wavelength of Brackett series of hydrogen atom is ...... [R=1.097xx10^(7)m-1]
