Answer:
Conservation of angular momentum
Explanation:
When the objects spread in universe after big bang, because of the tremendous force , they gained angular momentum and started to rotate. Since, then the object continue to rotate on their axis because of conservation of angular momentum. In vacuum of space there no other forces that can stop these rotation, therefore, they continue to rotate.
Answer:
0.0000109261200583 s
0.0109261200583
Explanation:
= Distance from right ear = 3 m
s = Distance between ears = 15 cm
v = Speed of sound in air = 343 m/s
Distance between the left ear and the bird

Time

Time difference would be
