This much depends on the properties of the plastic.
Foam will reflect little and absorb much.
Hard plastic will reflect much and absorb little.
Soft plastic will absorb more than hard plastic and reflect more than foam.

1000 kg aluminium oxide contain 470,588 kg aluminium.
Aluminium is called "एल्यूमिनियम" (aluminium) in Hindi.
The valence of aluminium is 3+.
Aluminium is a metal (an element), not an alloy. This means that it's only made up of aluminium atoms. It has no other impurities in it. Aluminium ore is called bauxite. This has aluminium plus other substances in it, but aluminium on its own is a metal with just aluminium atoms in it.

While neither are particularly good for allowing sound through the aluminium would likely allow it through better being a lighter, less tightly packed, metal.

absorbe sun for warmth and eat bactiera.
yes
No, mirrors reflect the light instead of absorbing it.
Sound travels faster through aluminum than glass because aluminum has a higher speed of sound due to its higher stiffness and density compared to glass.
proteins are absorbe din form of little particles.
Aluminium is actually an element, so the only element in aluminium is aluminium.
Aluminium. Aluminium. Aluminium.
