Q: Answer the following question given this paragraph: Gamma emission is the release of energy in the form of high energy electromagnetic waves. Q: What is the release of energy in the form of high energy electromagnetic waves? A: | OPTIONS:
- x-ray emission
- normal emission
- transient emission
- gamma emission
A: gamma emission

Q: Answer the following question given this paragraph: Figure 6.18 The diagram shows angular momentum for a circular motion. Q: The motion of stars in galaxies imply that there is about 10 times as much what as in the luminous objects we can see? A: | OPTIONS:
- density
- heat
- light
- mass
A: mass

Q: Answer the following question given this paragraph: A dipole occurs when two opposite charges are separated by some amount of distance. We have already seen dipoles in the form of polar bonds. For example, each O-H bond in water is an example of a dipole; the partial positive charge on hydrogen is separated from the partial negative charge on oxygen by the length of the bond. A molecular dipole is the geometric sum of all the individual bond dipoles in a molecule. In order for a molecule to have a dipole, it must have at least one polar bond. However, not all molecules with polar bonds have an overall molecular dipole. Sometimes the dipoles within a molecule will effectively cancel each other out, giving a zero net molecular dipole. This is often seen in symmetrical molecules. Q: What occurs when two opposite charges are separated by some amount of distance? A: | OPTIONS:
- particle
- radioactivity
- diffusion
- dipole
A: dipole

Q: Answer the following question given this paragraph: Minerals can form various shapes. Polygons are pictured below ( Figure below ). The shapes form as the minerals are broken along their cleavage planes. Cleavage planes determine how the crystals can be cut to make smooth surfaces. People who cut gemstones follow cleavage planes. Diamonds and emeralds can be cut to make beautiful gemstones. Q: The shapes of minerals form as they are broken along what planes? A: | OPTIONS:
- parallel planes
- sedimentary planes
- calcium planes
- cleavage planes
A: cleavage planes
