The correct answer is "provide for the common defence."
According to the Preamble of the U.S Constitution, the aforementioned part about providing for the common defence actually means that the nation should be well prepared against foreign interventions of any kind.
This kind of preparation does not only refer to military preparation but also refers to protecting the country at any costs from external forces.
Concept of effect:
The venturi vessel is simply implemented in the various procedures to obtain the increased value of velocity,v by constriction of the vessel's diameter or the total area required for the flow of liquids inside the vessel.And the decrease due to the constriction of the vessels area required for the flow of liquids.
But, we are provided we the given data in order to find the resultant value for the pressure,P inside the vessel.
<u>Given data:</u>
V=90 m/sec(the velocity,v at the inlet),
At=0.005,
V=90 m/sec,
∫∞=1.23 kg/m³,
V₁=√(P₁-P₂)/∫infinity[(area,A₁/final year,A)⁻¹],
Pressure,ΔP=1913.31 N/m².
<span>Stage 2 countries (developing nations) will have more males than females, on average. This is because there is a higher birth rate than death rate, and the birth rate is increasing rapidly. Due to this, there is a high number of women who are still dying during the birth process, and it leads to fewer women in the overall population.</span>
