Answer:
Buwaya
Explanation:
Constellations are the patterns imagined by joining stars together. Ancient people used to imagine these patterns and further related the appearance of constellations with natural phenomenon. Similarly constellations can also be related with a particular season depending upon the visibility. For example, Orion signifies the start of the winters in Northern hemisphere.
The rainy season in Philippines starts in the month of June the same time when Buwaya (local name given to the box in Pegasus constellation) starts being seen in the sky after a brief period of disappearance from the sky.
Answer:
Explanation:
When two coherent light beams travel different paths and arrive at a point , there will be difference in the length of path travelled by them . If this difference is zero then both will reinforce each other and their brightness will add up . Hence there will be constructive interference .
If their path difference is not zero but it is equal to odd multiple of their half wavelength like λ / 2 , 3 λ / 2 , 5 λ /2 , 7 λ /2 etc , then instead of reinforcing each other , they will destroy each other . This is called destructive interference . As a result of it , darkness will prevail at the point where they meet or interfere.
Answer: Objects falling through a fluid eventually reach terminal velocity. At terminal velocity, the object moves at a steady speed in a constant direction because the resultant force acting on it is zero.
