Given,
The initial inside diameter of the pipe, d₁=4.50 cm=0.045 m
The initial speed of the water, v₁=12.5 m/s
The diameter of the pipe at a later position, d₂=6.25 cm=0.065 m
From the continuity equation,
Where A₁ is the area of the cross-section at the initial position, A₂ is the area of the cross-section of the pipe at a later position, and v₂ is the flow rate of the water at the later position.
On substituting the known values,
Thus, the flow rate of the water at the later position is 5.99 m/s

Answer:
Below
Explanation:
The strength of Earth’s gravity decreases as an object gets farther from Earth. <===== this is the only statement that is true
Explanation:
Power = work / time
Power = force × distance / time
P = (12 kg × 10 m/s²) (8 m) / (10 s)
P = 96 Watts
Answer:
The correct option is: 4. its ionization energy decreases
Explanation:
Ionization energy refers to the energy required to pull a valence electron completely from the valence shell of a gaseous atom.
Now, in the <u>periodic table of chemical elements</u>, as we down a group, the atomic radius increases, so the effective nuclear charge experienced by the valence electron decreases. Therefore, the <u>ionization energy decreases</u><u>, down the group.</u>
As we across a period, the atomic radius usually decreases, so the effective nuclear charge experienced by the valence electron increases. Therefore, usually the <u>ionization energy increases</u><u>, across the period.</u>
<u>Therefore, as the atomic radius increases, the effective nuclear charge experienced by the valence electron decreases and thus the ionization energy also decreases.</u>
