Sound travels faster through liquids than air.
Sound travels faster through solids (that are elastic) than liquid or air.
Answer:
food web
Explanation:
it shows the interconnected relationships, and it also shows the trophic level for the following organism
27.0 g
Explanation:
The density of a substance tells you the mass of exactly one unit of volume of said substance.
In your case, aluminium is said to have a density of
density Al
=
2.70 g
.
cm
−
3
This tells you that every
1 mL
of aluminium has a mass of
2.70 g
.
All you have to do now is use the density of aluminium as a conversion factor to go from cubic centimenters of aluminium to grams
10.0
cm
3
⋅
2.70 g
1
cm
3
=
27.0 g

The answer is rounded to three sig figs.
It is to be noted that the Area of the Triangle formed by the points of intersection of the Parabola derived from the equation y = a(x-3) (x+2) with the derived coordinates is 12.
<h3>
What is a Parabola?</h3>
In mathematics, a parabola is a symmetrical open plane curve generated when a cone meets a plane parallel to its side.
Under the influence of gravity, a projectile's journey follows a curve of this shape.
Solution:
Step I - recall that y=a(x-3)(x+2)
This means that the base of the triangle is: 3-(-2) = 5
It's Height is = 6a. We arrive at this value when we make x = 0 and utilize the absolute value of the derivation.
Given that the area of a triangle is:
y=a(x-3)(x+2), we therefore have the following equation:
12 = 1/2 * 5 * 6 * A
If A = 4/5, then the solution to our equation comes to 12.
