Answer the following question given this paragraph: An electromagnetic wave begins when an electrically charged particle vibrates. This causes a vibrating electric field, which in turn creates a vibrating magnetic field. The two vibrating fields together form an electromagnetic wave. Q: An electromagnetic wave begins with what movement by an electrically charged particle? Choices: - acceleration - diffusion - momentum - vibration A:
(A).
vibration
Ques:Answer the following question given this paragraph: Helium may seem to be an exception, since it has only two valence electrons. This has to do with the fact that the n = 1 energy level has one s orbital and no p orbitals. As a result, the first energy level can be completely filled by just two electrons. It is the presence of a filled valence shell that gives noble gases their unusual stability, not anything intrinsic about the number 8. In addition to helium, the first few elements such as lithium, beryllium, and boron, have a particularly stable configuration with a pair of valence electrons rather that an octet. Q: How many valence electrons does helium have? Choices: - Five - six - three - two A:

Ans:two
Ques: Answer the following question given this paragraph: The asthenosphere is below the lithosphere. The asthenosphere is also in the upper mantle. This layer is solid, but it can flow and bend. A solid that can flow is like silly putty. Q: Which layer is found below the lithosphere? Choices: - troposphere - magnetosphere - stratosphere - asthenosphere A:
Ans:
asthenosphere
