Answer:
The flow diameter decreases.
Explanation:
From continuity equation,
Q = AV = constant
Where A is the area of the pipe which is proportional to its diameter.
V is the velocity of flow of fluid.
Q is the flow rate.
Let us consider the flow rate through the pipe. Assuming a steady state flow, if the velocity should increase, then the diameter will decrease.
For the flow leaving the pipe and descending to the floor, the flow is accelerated under gravity as it leaves the pipe. This acceleration causes its velocity to increase and consequently causing a reduction in the flow area. The result is the narrowing of the water that flows towards the floor (provided the flow remains laminar).
Answer:
e). The ratio is not given
Explanation:
<u>Capacitance of a capacitor</u>
The expression for the capacitance of a capacitor with di electric material is given as
C=KεA/d
where
ε=permittivity of di electric
C= capacitance in farads
A= Area of plate
d= separating distance
K= dielectric constant
let the distance in capacitor B be 1mm
therefore the distance in A is 0.5mm
For the first (A) capacitor
C1=8εA/0.5
C1=16εA
For the Second (B) capacitor
C2=8εA/1
C2=8εA
the ratio of the capacitance of A to B
=C1/C2
=16εA/8εA
=2/1
=2
