Ques: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:

Ans:opposite polarization

Ques:Q: What makes up most of the inside of a plant? Read this paragraph and choose the correct option from the provided answers: In normal faults , the hanging wall drops down relative to the footwall. Normal faults are caused by tension that pulls the crust apart. This causes the hanging wall to slide down. Normal faults can build huge mountain ranges in regions experiencing tension ( Figure below ). Choices: - star tissue - animal tissue - mitochondria - ground tissue A:

Ans:ground tissue

Ques:Q: Since 1900, four of the five earthquakes of the greatest magnitude occurred near what appropriately nicknamed pacific location? Read this paragraph and choose the correct option from the provided answers: Earthquakes with a magnitude in the 9 range are rare. The United States Geological Survey lists five such earthquakes on the moment magnitude scale since 1900 (see Figure below ). All but one, the Great Indian Ocean Earthquake of 2004, occurred somewhere around the Pacific Ring of Fire. Choices: - shower of fire - quake epicenter - seismic zone - ring of fire A:

Ans:
ring of fire
