Which materials, including polystyrenes, can be recycled? polymers thermoplastics ceramics composites

Polymers , thermoplastics.

Explanation:

Polymers like thermoplastic polymers can be recycled because they can be melted easily but thermosetting polymer can not be recycled because of their high melting point. Ceramics due to their high melting point are not recycled.

Thermoplastic composites can be recycled but thermoseting composites are not recycled. Composites are mix of two or more type of material having different physical and chemical properties.

an ion is a charged atom or molecule. it is charged because the number of electrons do not equal the number of protons in the atom or molecule. an atom can acquire a positive charge or a negative charge depending on whether the number of electrons in an atom is greater or less then the number of protons in the atom.

answer: d. a cme increases the amount of energy in the solar wind

explanation:

coronal mass ejections, also called cmes, are large clouds of plasma and magnetic field that erupt from the sun. only when the cloud is aimed at earth will the cme hit earth and therefore cause impacts. high-speed solar wind streams come from areas on the sun known as coronal holes.
