Frequency= speed/ wavelength
=0.5m/s divided 0.1.m
=5.0 Hz
The answer would be letter D.
<em>Labels that belong in the marked ares X, Y & Z include;</em>
X: Curves outward
Y: Image may be smaller than object
Z: Image is always virtual
<u>Since the rays never meet, the images formed by convex mirrors are always virtual and smaller than the object, and since they are smaller, the images appear to be further than they actually are.</u>

This is a diagram from above, the air resistance is oppose to movement, the bird is moving forward given its force is bigger.
