Answer:
Explanation:
Velocity is defined as the rate of change of displacement.
velocity is a vector quantity, that means it requires both magnitude and direction to completely explain the velocity.
For example, the velocity is 5 ms due east, it means an object is moving with speed 5 ms in the direction of east. We can say that the object covers the displacement of 5 m in one second due east.
Answer:
B

because if grocery store has a weak stability it will collapse when face strong naturally weather
The answer to this question would be A. Interference. This is because when two sounds with slightly different frequencies creates a periodic variation in volume.

Then you need to find x when n=1
or

≈θ for θ<<1 , so θ=
