I don't even know who that is but same fam
Explanation:
Hello,
Here i am using vectors
\vec{AB}=\vec{DC}=3\vec{i}+3\vec{j}AB=DC=3i+3j
==> AB//DC and AD//BC (definition of a translation)
The quadrilater ABCD is a parallelogram:
so
1) his diagonals have the same length;
2) his diagonals are cutting in the middle.
(these are proprieties of a parallelogram)
D
it creates new wetland areas
Answer:
Explanation:
From the given information:
weight of fiber = 3.0 g
weight of composite specimen = 4.0 g
specimen composite weight in water = 2.0 g
specific gravity of fiber = 2.4
specific gravity of matrix = 1.3
The weight of the matrix = weight of the composite - the weight of fiber
⇒ (4.0 - 3.0) g
= 1.0 g
The theoretical density of the composite can be determined by using the formula:
The experimental density is determined by using the equation:
The void fraction is:
= 0.1818
