If the water temperature had increased after submerging resistor B, which of the followi

ng statements would have been most accurate?

A.The fact that the water temperature increased after submerging Resistor B shows that resistor B is a thermistor.

B.The fact that the water temperature increased after submerging Resistor B shows that resistor B is not an ohmic device.

C.Since the measured current was the same when the initial water temperature was 23°C as when it was 25°C,resistor B is an ohmic device.

D.Since the measured current was the same when the initial water temperature was 23°C as when it was 25°C,resistor B is not a thermistor.

第7题

Unmanned spacecraft taking images of Jupiter&39;s moon Europa have found its surface to be

very smooth with few meteorite craters. Europa&39;s surface ice shows evidence of being continually resmoothed and reshaped. Cracks, dark bands, and pressure ridges (created when water or slush is squeezed up between 2 slabs of ice) are commonly seen in images of the surface. Two scientists express their views as to whether the presence of a deep ocean beneath the surface is responsible for Europa&39;s surface features.

Scientist 1

A deep ocean of liquid water exists on Europa. Jupiter&39;s gravitational field produces tides within Europa that can cause heating of the subsurface to a point where liquid water can exist. The numerous cracks and dark bands in the surface ice closely resemble the appearance of thawing ice covering the polar oceans on Earth. Only a substantial amount of circulating liquid water can crack and rotate such large slabs of ice. The few meteorite craters that exist are shallow and have been smoothed by liquid water that oozed up into the crater from the subsurface and then quickly froze.

Jupiter&39;s magnetic field, sweeping past Europa, would interact with the salty, deep ocean and produce a second magnetic field around Europa. The spacecraft has found evidence of this second magnetic field.

Scientist 2

No deep, liquid water ocean exists on Europa. The heat generated by gravitational tides is quickly lost to space because of Europa&39;s small size, as shown by its very low surface temperature (–160°C). Many of the features on Europa&39;s surface resemble features created by flowing glaciers on Earth. Large amounts of liquid water are not required for the creation of these features. If a thin layer of ice below the surface is much warmer than the surface ice, it may be able to flow and cause cracking and movement of the surface ice. Few meteorite craters are observed because of Europa&39;s very thin atmosphere; surface ice continually sublimes (changes from solid to gas) into this atmosphere, quickly eroding and removing any craters that may have formed.

1.Which of the following best describes how the 2 scientists explain how craters are removed from Europa&39;s surface?

A.Sublimation;Filled in by water

B.Filled in by water;Sublimation

C.Worn smooth by wind;Sublimation

D.Worn smooth by wind;Filled in by water
