Ques: Q: What effect causes winds and currents to form circular patterns? Read this paragraph and choose the correct option from the provided answers: The Coriolis effect causes winds and currents to form circular patterns. The direction that they spin depends on the hemisphere that they are in. Choices: - horse latitudes - jet stream - centrifugal effect - coriolis effect A:
Ans: coriolis effect

Ques: Q: In the lens makers' equation, diverging lenses and virtual images are associated with what kinds of numbers? Read this paragraph and choose the correct option from the provided answers: When using the lens makers equation, remember that real things get positive numbers and virtual things get negative numbers. Thus, diverging lenses and virtual images get negative numbers. The object distance is always positive. Choices: - positive numbers - variable numbers - fractional numbers - negative numbers A:
Ans: negative numbers

Ques: Q: What does the geiger counter detect? Read this paragraph and choose the correct option from the provided answers: You generally can't see, smell, taste, hear, or feel radiation. Fortunately, there are devices such as Geiger counters that can detect radiation. A Geiger counter, like the one pictured in the Figure below , contains atoms of a gas that is ionized if it encounters radiation. When this happens, the gas atoms change to ions that can carry an electric current. The current causes the Geiger counter to click. The faster the clicks occur, the higher the level of radiation. You can see a video about the Geiger counter and how it was invented at the URL below. Choices: - vibration - convection - moisture - radiation A:
Ans: radiation

Ques: Q: What is group 16 of the periodic table referred to? Read this paragraph and choose the correct option from the provided answers: Group 16 of the periodic table is also called the oxygen group. The first three elementsoxygen (O), sulfur (S), and selenium (Se)are nonmetals. They are followed by tellurium (Te) ( Figure below ), a metalloid, and polonium (Po), a metal. All group 16 elements have six valence electrons and are very reactive. Oxygen is a gas at room temperature, and the other elements in the group are solids. Choices: - sulfur group - dioxide group - acid group - oxygen group A:
Ans:
oxygen group
