Explanation:
Using the concept of continuity equation
for flow through pipes
Where,
A = Area of cross-section
V = Velocity of fluid at the particular cross-section
given:
a)
substituting the values in the continuity equation, we get
or
or
b)
substituting the values in the continuity equation, we get
or
or
c) we have,
Discharge
thus from the given value, we get
Also,
Discharge
given time = 1 hour = 1 ×3600 seconds
substituting the value of discharge and time in the above equation, we get
or
volume of flow =
Answer:
false
Explanation:
the president can over turn any ruling made by any governing body not just the supreme court
Answer: Option (b) is the correct answer.
Explanation:
Metals are malleable and ductile, that means, metals can be beaten into thin sheets and they can be drawn into thin wires.
While showing the property of malleability and ductility, the bonds between metals did not break as there is only change in the shape of metal.
Thus, we can conclude that out of the given options, in metals, the properties of malleability and ductility are explained by the fact that metallic atoms can roll over without breaking their bonds.
