Question: Q: What type of polarization does a negative object create> Read this paragraph and choose the correct option from the provided answers: Figure 18.15 Both positive and negative objects attract a neutral object by polarizing its molecules. (a) A positive object brought near a neutral insulator polarizes its molecules. There is a slight shift in the distribution of the electrons orbiting the molecule, with unlike charges being brought nearer and like charges moved away. Since the electrostatic force decreases with distance, there is a net attraction. (b) A negative object produces the opposite polarization, but again attracts the neutral object. (c) The same effect occurs for a conductor; since the unlike charges are closer, there is a net attraction. Choices: - common polarization - simple polarization - negative polarization - opposite polarization A:
Answer: opposite polarization

Question: Q: What is the first stage of cellular respiration? Read this paragraph and choose the correct option from the provided answers: The first stage of cellular respiration is glycolysis . It takes place in the cytosol of the cytoplasm. Choices: - electron transport - Krebs cycle - photosynthesis - glycolysis A:
Answer: glycolysis

Question: Q: In a displacement graph, the slope of the line is the average what? Read this paragraph and choose the correct option from the provided answers: Example 2.17 Determining Average Velocity from a Graph of Displacement versus Time: Jet Car Find the average velocity of the car whose position is graphed in Figure 2.47. Strategy The slope of a graph of x vs. t is average velocity, since slope equals rise over run. In this case, rise = change in displacement and run = change in time, so that. Choices: - direction - speed - time - velocity A:
Answer:
velocity
