A bird flies at 12.5 meters per second. the wind speed is 4.5 meters per second. what is the speed of the bird when it flies with the wind?

17m/s

Explanation:

Given parameters:

Speed of the bird  = 12.5m/s

Speed of the wind  = 4.5m/s

Unknown:

Speed of the bird when it flies with the wind = ?

Solution:

The speed of the bird when it flies with the wind is the sum of the speed of the bird and the speed of the wind.

  Speed of the bird with wind  = 12.5m/s + 4.5m/s  = 17m/s

an adaptation is a change or process by which an organism takes to be better suited for its environment. for example; migration is a behavioral adaptation, this is needed because birds are not built to last extremely cold climates. there are different adaptations because there are different species needing to adjust to different things, bears don't migrate; they hibernate.

when the displaced particles are perpendicular to the direction the wave travels, is called a transverse wave, whereas in longitudinal wave the displace practices are parallel to the direction of the wave.
