Answer:
a. Composition of Vector.
Explanation:
When a bird flies in the air, it stretches its wings into air and this movement helps it move in a certain direction. This is an example of composition of vector. Air strikes the wings in opposite direction and bird wing movement helps it move against the wind.
Good afternoon!
An example can be migrating salmon moving material across ecosystem boundaries.
Answer:
The composition of Composite of Volume basis is 2.154% Copper and 97.83% Rubber.
Explanation:
Let us assume that the total mass of composite is 100 lbm So as per the given conditions
- 15 lbm is copper and 85 lbm is rubber.
- Density of rubber is 70 lbm/ft3
- Specific gravity of Copper is 9
So As per the formula of specific gravity

here density of water is 62.4 lbm/ft3
Solving for Density of Copper gives

For composition on volume basis, volume of individual components and composite are calculated as

The composition is given as

So the composition of Composite of Volume basis is 2.154% Copper and 97.83% Rubber.
