Answer:
1.435 x 10^-4 cm^3/s
Explanation:
coefficient of viscosity, η = 0.028 poise
Radius, R = 0.008 cm
length, l = 2 cm
Pressure, P = 5000 dyne/cm^2
The Poiseuille's formula is given below
Where, V is the rate of flow, that means volume flowing per second
V = 1.435 x 10^-4 cm^3/s
Thus, the rate of flow is 1.435 x 10^-4 cm^3/s.
The state of the atmosphere at a given place and time as regards to heat, dryness sunshine, wind, rain, etc.

(18.75 m) x (the steady force applied to the wagon all the way, in Newtons) .
The unit is Joules .
Answer:
103.70 nm
Explanation:
The minimum thickness of the film is given by 
where 
is the wavelength and n is the index of the refraction
We have n =1.35
Wavelength 
So the minimum thickness of the film
