Verified Answer

A sample of ordinary hydrogen gas in a discharge tube was seen to emit...

⇒

.....(i)
For

the

-line is at 6562.80 Å. thus equation (i) implies with M = 1836 m, λ = 6562.80 Å;

...(ii)
For unknown impurity, the

- line is at 6561.01 Å thus M = x x 1836 m (H ere, we have assum ed the m ass of nucleus of unknown impurity equal to x times mass of proton or hydrogen nucleus). λ = 6561.01 Å;

...(iii)
Now. dividing equation (ii) by (iii), we get 1.000272824

⇒

Hence, the mass o f nucleus is 2 times that of

Out o f the given options, nucleus

has the mass equal to two times the nuclear mass of

Water is discharged at atmospheric pressure from a large reservoir through a long pipe of diameter d and length L. The height of the free surface of the reservoir from the discharge point is h meters. The Darcys friction factor of the pipe is 0.002. Neglect the velocity inside the reservoir as the reservoir is very large. Given, L = 20m, d = 40mm, density of water = 1000kg/m3 and flow rate is Q=4π x 10-3m3/s.Assume gravitational acceleration, g = 10 m/s2.
