Q: What is friction that acts on objects that are moving through a fluid? Read this paragraph and choose the correct option from the provided answers: Fluid friction is friction that acts on objects that are moving through a fluid. A fluid is a substance that can flow and take the shape of its container. Fluids include liquids and gases. If you've ever tried to push your open hand through the water in a tub or pool, then you've experienced fluid friction. You can feel the resistance of the water against your hand. Look at the skydiver in the Figure below . He's falling toward Earth with a parachute. Resistance of the air against the parachute slows his descent. The faster or larger a moving object is, the greater is the fluid friction resisting its motion. That's why there is greater air resistance against the parachute than the skydiver's body. Choices: - fluid catalyst - fluid temperature - mass friction - fluid friction A:
(A).
fluid friction

Q: What is stacked in layers in "layer cake geology"? Read this paragraph and choose the correct option from the provided answers: Geologists say that the Grand Canyon ( Figure above ) has "layer cake geology. " This is because the rock strata are in layers. They are extremely easy to see. Sedimentary rocks are like a book that tells the story of the environment in which they formed. Rock units can be traced across large expanses. Looking down into the Grand Canyon, you get a sense of the vastness of space and of time. Choices: - sediment - soil - horizontal stata - rock stata A:
(A).
rock stata

Read this paragraph and choose the correct option from the provided answers: Stems hold plants upright, bear leaves and other structures, and transport fluids between roots and leaves. Choices: - branches - flowers - leaves - stem A:
(A).
