Answer:

$539\pi cm^{3}$

Step-by-step explanation:

the volume of a cylinder is $V=\pi r^{2} h$

Let r=7cm and h=11cm

V= $7^{2}$ ·11· $\pi$

V=539 $\pi$ $cm^{3}$ or 1693.31844 $cm^{3}$

/2 /2

a=2.3

b+2=4.6

-2 -2

b=2.6

c/2=4.6

*2 *2

c=9.2

d-2=4.6

+2 +2

d=6.6

e+3/8=2

-3/8 -3/8

e=1 5/8

A potential energy function is given by U = A x3 + B x2 − C x + D . For positive parameters A, B, C, D this potential has two eq

Ivenika [448]

Answer:

7.8655

Step-by-step explanation:

Given the functionl

$U=Ax^3+Bx^2-cx+D$

Where,

$A=1.45J/m^3\\B=2.85J/m^2\\c= 1.7J/m\\D=0.6J$

We have, replacing,

$U=1.45x^3+2.85x^2-1.7x+0.6$

We need to derivate and verify for stable equilibrum that,

$\frac{d^2 U}{dx^2}>0$

Then,

$U'(x) = 4.32x^2+5.7x-1.7$

Roots in,

$x_1=-1.57008\\x_2=0.250636$

We obtain U"(x), then we have

$\frac{d^2U}{dx}=8.64x+5.7$

For $x=-1.57, U"(x)=-7.86549$ Unestable

For $x=0.250636 U"(x)=7.8655>0$ Stable
