deep=4 m
Area of base 
hydro static Pressure on bottom

Force on bottom
Now pressure at the side wall

where
is the mean length of wall = 4 m

Answer:
The position of stable equilibrium is -a
And the period of small oscillations must be: c/(ma^3)
Explanation:
Since the potential is:

We first look for a position of stable equilibrium. This posiiton must satisfy two considtions, that the first derivative of the potential must vanish at this point and the second derivative must be positive.

Which vanish for
x = a ; x =-a
The second derivative of V(x) is:

And:

Therefore:
a)
The position of stable equilibrium is -a
And the period of small oscillations must be:

(c/(ma^3))^1/2
b)
Let's find the maximum amplitude if the particle starts at this point with velocity v
If this is the case, the total energy will be:
(mv^2)/2
And the maximum amplitude will be
x = a^3/c mv^2 = (m v^2 a^3)/ c
Answer:
24525 N
Explanation:
The <em>mass</em> of an object is a fundamental property of the object.
The <em>weight</em> of an object is the force of gravity on the object.
This is defined as follows
Weight (W)= mass(m) × weight of a unit mass(g)
( gravitational field intensity = g)
Assuming g= 9.81 ms⁻²,
W = mg
= 2500×9.81 = 24525 N
Answer:
There are three kinds of rock: igneous, sedimentary, and metamorphic.
<h3>since their movement is always free pendicular to the force magnetic force no work and the electrons velocity stays constant since the force is F=QVB a constant magnetic field and another from field force of content magnitude always directed perpendicular to its motion the result is a circle Orbit.</h3>
