Kinetic energy remains conserved in an elastic collision.
The correct answer from the choices given is the third option. Covalent compounds have low boiling points. Also, their melting points are low. Covalent bonds have relatively low attractions which results to these properties. The bonds are easily broken by taking energy or adding energy.
Answer:
B. Line 2 has a mistake
Explanation:
1. All electromagnetic waves are made of both electric and magnetic fields (hence the name electromagnetic).
2. All electromagnetic waves are transverse, and not longitudinal.
3. All electromagnetic waves can travel through space because they do not need particles to travel (like sound waves).
4. Electromagnetic waves all travel at the speed of light (299 792 458 m/s).
