Explanation:
Given:
volume of urine discharged, 
time taken for the discharge, 
diameter of cylindrical urethra, 
length of cylindrical urethra, 
density of urine, 
a)
we have volume flow rate Q:
& 
where:
cross-sectional area of urethra
velocity of flow
b)
The pressure required when the fluid is released at the same height as the bladder and that the fluid is at rest in the bladder:
I think it should be a cold
Helium exhibits more visible emission lines or spectral lines than hydrogen is due to the fact that helium has two electrons compared to hydrogen which only has one electron. The greater the chance of the energy levels falling within the visible range when there's more energy level. Spectral lines are usually the result of the interaction of quantum system, usually atoms but can also be the molecules or the atomic nuclei sometimes together with a single photon. Whenever photon has the right amount of energy in order to allow changes in energy state, the system, or the electron changing orbitals will absorbed the photon, then will be emitted whether in same frequency with the original of in cascade.
