Q: 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: Q: What is the process when animals maintain an internal temperature? Read this paragraph and choose the correct option from the provided answers: Choices: - osmoregulation - bioaccumulation - homeostasis - thermoregulation A:
A: thermoregulation

Q: Q: Pressure, volume, and temperature are related by which law? Read this paragraph and choose the correct option from the provided answers: Pressure, volume, and temperature are related by the combined gas law. Choices: - Law of Conservation - law of inertia - Murphy's Law - gas law A:
A: gas law

Q: Q: A catalyst can increase the rate of what, in general? Read this paragraph and choose the correct option from the provided answers: A catalyst is a substance that increases the rate of a chemical reaction. The presence of a catalyst is one of several factors that influence the rate of chemical reactions. (Other factors include the temperature, concentration, and surface area of reactants. ) A catalyst isn't a reactant in the chemical reaction it speeds up. As a result, it isn't changed or used up in the reaction, so it can go on to catalyze many more reactions. Choices: - mechanicl reaction - carbon reaction - consumption reaction - chemical reaction A:
A: chemical reaction
