Answer:
'The bottom of a pond appears raised.' due to refraction phenomenon.
Explanation:
- Whenever light travel through different medium it bends its path. so when the light travels into pond i.e air(rarer) to water (denser) it bends its path creating an illusion.
- The bending of this light ( away the normal) and again towards the normal after reflecting from bottom of pond creates an vision as if the bottom of pond is raised a little.
- This phenomenon is called as the refraction phenomenon.
The answer is A a change in time
Speed of sound = 340 m/s
Time taken for sound to reach observer = 3.2 seconds
Height = speed x time
= 340 x 3.2
= 1,088 meters
Answer:
When a motorcycle takes a turn, centrifugal force—in this case, friction between the tires and the road—pushes it towards the center. This basic physics explains why riders can lean into turns without falling. However, when an outside force disrupts or unbalances these forces, the vehicle crashes. that is the only one that I can answer for you. :)
