Answer:
polar molecules are molecules that have an unequal distribution of charges. nonpolar molecules, the type of covalent bond are equally shared between two atoms or elements producing no charged ends
Answer:
41.5 m/s
Explanation:
Since there are no external forces, momentum must be conserved.
Momentum P = mv.
Total momentum before the collision:
Total momentum after the collision:
solving for v:
Light is a form of electromagnetic radiation with a wavelength which can be detected by the human eye. It is a small part of the electromagnetic spectrum and radiation given off by stars like the sun. Animals can also see light. The study of light, known as optics, is an important research area in modern physics.
The statement which best describes how light waves travel in an uniform medium is in straight lines. The correct answer will be A.
