Q: What do you call any force that makes something move in a circle? Read this paragraph and choose the correct option from the provided answers: Centripetal Force is an umbrella term that refers to any force that makes something move in a circle. Examples of forces that can be centripetal forces are as follows: Gravity (the gravity between the Earth and Sun causes the Earth to go in a circle), Friction (the friction force between a car's tires and the road causes the car to turn), Tension (when swinging a bucket around in a circle by holding onto the string, the tension of the string is the centripetal force). Choices: - cyclical - tangential force - momentum - centripetal force A:
centripetal force

Q: All cells have voltages across their what? Read this paragraph and choose the correct option from the provided answers: Choices: - display membranes - ribosomes - nuclei - plasma membranes A:
plasma membranes

Q: Q: What substances, which serve as catalysts, are involved in most of the chemical reactions that take place in organisms? Read this paragraph and choose the correct option from the provided answers: Enzymes are involved in most of the chemical reactions that take place in organisms. Choices: - proteins - vitamins - carbohydrates - enzymes A:
A: enzymes

Question: Q: About how many days does it take the moon to make one orbit around the earth? Read this paragraph and choose the correct option from the provided answers: The Moon does not produce any light of its own. It only reflects light from the Sun. The Moon has phases because it orbits around Earth. One orbit takes about 28 days. As the moon moves around Earth, different parts of it appear to be lit up by the Sun. The Moon sometimes appears fully lit and sometimes completely dark. Sometimes it is partially lit. The different appearances of the Moon are referred to as phases of the Moon ( Figure below ). Choices: - 21 - 30 - 22 - 28 A:
Answer: 28

Q: Streamlines are smooth and continuous when flow is laminar, but break up and mix when flow is what? Read this paragraph and choose the correct option from the provided answers: 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. Choices: - atmospheric - volcanic - slow - turbulent A:
**Answer**
turbulent
