Answer: B. sled dogs face many types of obstacles in the North, including extreme cold, challenging terrain, and unpredictable weather. The dogs run through a land that gets so cold that the ocean freezes Into ice. The terrain is challenging, as dogs can climb mountains of 5,000 feet and swim through ice fioes. The weather can change quickly, resulting in ice storms and blizzards. The extreme temperatures molt terrain, and bad weather are all obstacles that sled dogs face in the North.
Explanation:
The text-based response that best answers the question: "What types of obstacles do sled dogs face in the North?" is option B.
Option A is incorrect as the option provided didn't explain the obstacles that the sled dogs faced in the North.
Option C is incorrect as it didn't explain the kind of obstacles that sled dogs face but rather, it explains how they can survive cold.
Option D is incorrect as the obstacles discussed were general as it wasn't specific to the North.
Option B is correct as it gives a detailed analysis on the kind of obstacles that the dogs face and explained it in detail.
Answer: Both passages are written for textbooks so C is youre
answer.
Explanation: this is correct

The objects that produce large amplitude waves are Stars, Large machines, Rocks falling from the mountain, Earthquakes, Volcanoes
The objects producing small amplitude waves include ping-pong ball, Tuning fork, stones, Speakers, Spring
<u>Explanation</u>:
The wave's amplitude is characterised by the ultimate displacement of an object from its median position. Generally, wave with high energy (or the waves emanating from big bodies or high energy bodies) are high amplitude waves. Since the body has a high amount of energy, it produces a comparatively large amount of displacement of the particle. hence the high amplitude.
Similarly, small bodies or bodies with less energy produces a low amplitude wave. This also can be understood in terms of displacement of the particle from its mean position.
I think it would be 18 because it moved a total of 18=12+6
