Answer:
<h3>Density = 0.5 g/cm³</h3>
Explanation:
Density of a substance can be found by using the formula

From the question
mass = 32g
To find the density we must first find the volume of the block
From the question the block is a cuboid
Volume of cuboid = length × width × height
length = 8 cm
width = 4 cm
height = 2 cm
Volume of block = 8 × 4 × 2 = 64 cm³
Substitute the values into the above formula and solve for the density
That's....

We have the final answer as
Density = 0.5 g/cm³
The block will float because it's density is less than the density of water which is
1 g/cm³
Hope this helps you
Explanation:
With respect to the mass transport mechanism in mixing, two fluids flow tangentially into the chamber and the radial component of velocity grows because fluids tend to flow through the outlet channel. These two components result in an overall rotating flow field inside the chamber

Answer:
the answer is Respiratory epithelium, or airway epithelium, is a type of ciliated columnar epithelium found lining most of the respiratory tract as respiratory mucosa, where it serves to moisten and protect the airways. But I don't see that option here.
