Answer:
The answer is: Pressure increases linearly with the depth
Explanation:
In this case, the definition of pressure is:
where F = mg is the weight of the fluid over the body, and A is the area of the surface to which the force is exerted. If we consider , then
.
Volume can be expressed as V = A*h, where A is the cross section of the column of the fluid over the body and h is the height of the column, in other words, the depth.
So
,
which means that pressure increases linearly with the depth in a factor of .

Answer:
The speed of its center of mass =
Explanation:
Consider the potential energy at the level of center of mass of rod below the pivot=0
Mass of uniform rod=M
Length of rod=L
The rotational inertia about the end of a uniform rod=
Kinetic energy at the level of center of mass of rod below the pivot=
Kinetic energy at the level of center of mass of rod above the pivot=0
Potential energy at the level of center of mass of rod above the pivot=mgh
We have to find the center of mass ( in terms of g and L).
According to conservation of law of energy
Initial P.E+Initial K.E=Final P.E+Final K.E
Where
I=Moment of inertia
=Angular velocity
Substitute the values then we get
Now, we know that ,
Substitute the values then we get
Hence, the speed of its center of mass =
