Answer:
Velocity from second channel will be 1.6875 m/sec
Explanation:
We have given width of the channel , that is diameter of the channel 1 
= 12 m
So radius 
Speed through the channel 1 
Width , that is diameter of the channel 2 
So 
From continuity equation
So velocity from smaller channel will be 1.6875 m /sec
Answer:
Therefore, the brick appears to have an additional force pushing it upward.
Explanation:
When a brick is submerged in the water, it has two forces acting upon it. One force is the gravitational force or the weight of the brick, that acts downward. The weight force also acts on the brick when it is not in water. But, in water an additional force acts on the brick. This additional force is named as Buoyant Force. This force is equal to the weight of the water displaced by the brick. And this Buoyant Force acts on the brick in the upward direction. The formula for this force is given as follows:
Buoyant Force = (Density of Water)(Volume of Water Displaced)(g)
<u>Therefore, the brick appears to have an additional force pushing it upward.</u>

Density can be found when mass and volume is known. The density of 5 liter of water is 1000kg/m³.
<h3>What is density?</h3>
The density ρ of any substance is the ratio of mass m and its volume V.
ρ = m/V
Given is the mass of water as 5 kg and the volume is 5 liter.
as, 1 L = 10−³m³
So, 5 L = 5×10−³m³
Then, density would be
ρ = 5kg / 5×10−³m³
ρ = 1000 kg/m³
Thus, the density of 5l of water is 1000kg/m³.
