Answer the following question given this paragraph: Figure 9.24 (a) In the case of the wheelbarrow, the output force or load is between the pivot and the input force. The pivot is the wheel's axle. Here, the output force is greater than the input force. Thus, a wheelbarrow enables you to lift much heavier loads than you could with your body alone. (b) In the case of the shovel, the input force is between the pivot and the load, but the input lever arm is shorter than the output lever arm. The pivot is at the handle held by the right hand. Here, the output force (supporting the shovel's load) is less than the input force (from the hand nearest the load), because the input is exerted closer to the pivot than is the output. Q: In the case of the wheelbarrow, the output force or load is between the pivot and the what? Choices: - velocity force - Driving Force - density force - input force A:
input force
Answer the following question given this paragraph: We learned in the previous concept, "Scientific Explanations and Interpretations," that the average global temperature has been on the rise. Scientists know that carbon dioxide is a greenhouse gas . Greenhouse gases trap heat in the atmosphere. This leads us to a question:. Q: Where do greenhouse gases trap heat? Choices: - ground - space - altitude - atmosphere A:
atmosphere
Q: Answer the following question given this paragraph: energy. Red marrow is where hematopoiesisthe production of blood cellstakes place. Red blood cells, white blood cells, and platelets are all produced in the red marrow. Q: Red blood cells, white blood cells, and platelets are all produced where? Choices: - in yellow marrow - in synovial fluid - in collagen - in red marrow A:
A: in red marrow
Question: Answer the following question given this paragraph: Q: What membrane is populated by two types of photosystems that cooperate in the light reactions of photosynthesis? Choices: - choroid - chloroplasts - subcutaneous - thylakoid A:
Answer: thylakoid
*Question*
Answer the following question given this paragraph: It's much easier to precisely make mirrors than to precisely make glass lenses. For that reason, reflectors can be made larger than refractors. Larger telescopes can collect more light. This means that they can study dimmer or more distant objects. The largest optical telescopes in the world today are reflectors. Telescopes can also be made to use both lenses and mirrors. Q: What happens to old oceanic crust at convergent boundaries? Choices: - created - dissolves - emerges - destroyed A:
**Answer**
destroyed
(Question)
Answer the following question given this paragraph: Coal is a black or brownish-black rock that burns easily ( Figure below ). Most coal is sedimentary rock. The hardest type of coal, anthracite, is a metamorphic rock. That is because it is exposed to higher temperature and pressure as it forms. Coal is mostly carbon, but some other elements can be found in coal, including sulfur. Q: What element makes up the majority of coal? Choices: - iron - lead - silicon - carbon A:
(Answer)
carbon
