Answer:
Explanation:
a)
d = separation of the slits = 0.30 mm = 0.30 x 10⁻³ m
λ = wavelength of the light = 496 nm = 496 x 10⁻⁹ m
n = order of the bright fringe
D = screen distance = 130 cm = 1.30 m
= Position of nth bright fringe
Position of nth bright fringe is given as
For n = 1
For n = 2
For n = 3
b)
Position of nth dark fringe is given as
For n = 1
For n = 2
For n = 3
Answer:
speed of flow of blood in the blocked portion of the vessel is 9.18 vo
Explanation:
given data
diameter of the vessel = 67.0 %
to find out
what is its speed v expressed as a multiple of vo
solution
we know here that Plaque decreases diameter of the vessel by 67%
s here diameter in the blocked portion = 33% of diameter in unblocked portion so
we will apply here Continuity equation that is express as
Ao×Vo = A1×V1 ...................1
here Ao is Cross-sectional area of the cylindrical blood vessel that is =
and do is Diameter of the cylindrical blood vessel and vo is Speed of flow of blood in the blood vessel
and d1 is diameter of the vessel in the blocked portion of the vessel that is = 0.33 do and A1 is cross section area of the vessel in the blocked portion that is = and v1 is Speed of flow of blood in the blocked portion of the vessel
so now we put value in equation 1 we get
Ao×Vo = A1×V1
× vo = × v1
do²×vo = d1²×v1
do²×vo = d1²×v1
do²×vo = (0.33 do)²×v1
solve it we get
v1 = 9.18 vo
so speed of flow of blood in the blocked portion of the vessel is 9.18 vo
Net Force is Zero because both forces cancel each other out
