I think the answer is, density is the ratio of mass to volume. 

Density is the term used to describe the relation between mass of liquid to a volume.  A denser liquid is lighter.   <span>It can be observed on liquids that floa</span><span>t on tops of another like oil and water. </span>

Water<span> can </span>dissolve salt<span> because the positive part of </span>water<span> molecules attracts the negative chloride ions and the negative part of </span>water<span> molecules attracts the positive sodium ions. The amount of a substance that can </span>dissolve<span> in a liquid (at a particular temperature) is called the solubility of the substance. So the solute is the salt and the solvent is the water. I believe that is correct.</span>

An arch is in the shape of a parabola with its vertex at the top. It has a span of 100 feet and a maximum height of 40 feet. Fin
nexus9112 [7]

Answer:36.4 ft

Explanation:

Given

Span of Parabola L=100 ft

Maximum height h=40

suppose Parabola is of type

(x-x_0)^2=-4a(y-y_0)

where x_0,y_0 is the center of parabola

x_0=0, y_0=40

x^2=-4a(y-40)

at y=0

x^2=-4a\times (-40)

x^2=160a

x=\pm \sqrt{160a}

and it is given, 2x=100

x=50

\sqrt{160a}=50

a=15.625

thus x^2=-4a(y-40)

at x=15

15^2=-4\times 15.625(y-40)

y=36.4 ft

point) A tank in the shape of an inverted right circular cone has height 5 meters and radius 4 meters. It is filled with 4 meter
zysi [14]

Answer:

W = 907963.50 J = 907.96 J

Explanation:

Note: Refer to the figure attached

Now, from the figure we have similar triangles ΔAOB and ΔCOD

we have

\frac{5}{4}=\frac{x}{r}

or

r=\frac{4x}{5}

Now, the work done to empty the tank can be given as:

W = \int\limits^4_0 {(5-x)\rho\times g A} \, dx

or

W = \int\limits^4_0 {(5-x)1080\times 9.8 (\pi r^2)} \, dx

or

W = \int\limits^4_0 {(5-x)\times10584\times (\pi (\frac{4x}{5})^2)} \, dx

or

W = 6773.76\pi\int\limits^4_0 {(5-x)x^2)} \, dx

or

W = 6773.76\pi[\frac{5}{3}x^3-\frac{1}{4}x^4]^4_0

or

W = 6773.76\pi[\frac{128}{3}]

or

W = 907963.50 J = 907.96 J
