As one example, the cubic crystal system is composed of three different types of unit cells: (1) simple cubic , (2) face-centered cubic , and (3) body-centered cubic . These are shown in three different ways in the Figure below . Q: The cubic crystal system is composed of how many different types of unit cells? A:
A:
output: three

Answer the following question given this paragraph: As the fast-moving cold air mass keeps advancing, so does the cold front. Cold fronts often bring sudden changes in the weather. There may be a thin line of storms right at the front that moves as it moves. In the spring and summer, the storms may be thunderstorms and tornadoes. In the late fall and winter, the storms may bring snow. After a cold front passes, the cold air mass behind it brings cooler temperatures. The air is likely to be less humid as well. Can you explain why?. Q: What type of fronts often bring sudden changes in the weather, including different types of precipitation, depending on the season? A:

OPTIONS:
- stationary fronts
- occluded fronts
- warm fronts
- cold fronts

Answer: cold fronts

Problem: OPTIONS:
- atmospheric
- volcanic
- slow
- turbulent
Q: Answer the following question given this paragraph: Figure 12.11 shows schematically how laminar and turbulent flow differ. Layers flow without mixing when flow is laminar. When there is turbulence, the layers mix, and there are significant velocities in directions other than the overall direction of flow. The lines that are shown in many illustrations are the paths followed by small volumes of fluids. These are called streamlines. Streamlines are smooth and continuous when flow is laminar, but break up and mix when flow is turbulent. Turbulence has two main causes. First, any obstruction or sharp corner, such as in a faucet, creates turbulence by imparting velocities perpendicular to the flow. Second, high speeds cause turbulence. The drag both between adjacent layers of fluid and between the fluid and its surroundings forms swirls and eddies, if the speed is great enough. We shall concentrate on laminar flow for the remainder of this section, leaving certain aspects of turbulence for later sections. Q: Streamlines are smooth and continuous when flow is laminar, but break up and mix when flow is what? A:
Answer: turbulent
