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:
**Answer**
fluid friction

Q: What are compounds composed of only two elements called? Read this paragraph and choose the correct option from the provided answers: Binary compounds are compounds composed of just two elements. The simplest kind of decomposition reaction is when a binary compound decomposes into its elements. Mercury(II) oxide, a red solid, decomposes when heated to produce mercury and oxygen gas. Choices: - digital compounds - symbiotic compounds - kinetic compounds - binary compounds A:
**Answer**
binary compounds

Q: When is the rate of the forward reaction equal to the rate of the reverse reaction? Read this paragraph and choose the correct option from the provided answers: At equilibrium, the rate of the forward reaction is equal to the rate of the reverse reaction. Choices: - at conduction - before equilibrium - after equilibrium - at equilibrium A:
**Answer**
at equilibrium

Q: What do stored fats provide our body with for later use? Read this paragraph and choose the correct option from the provided answers: Fats are one type of lipid. Stored fat gives your body energy to use for later. It's like having money in a savings account: it's there in case you need it. Stored fat also cushions and protects internal organs. In addition, it insulates the body. It helps keep you warm in cold weather. Choices: - metals - hydrogen - water - energy A:
**Answer**
energy
