The correct answer is: <span>smaller than object, virtual and upright.
</span>
When the object is placed between the focal point and the vertex of a convex mirror, then the image formed will be <span>located behind the convex mirror. It will be virtual image and an upright image but reduced in size (i.e., smaller than the object)</span>

Answer:
V = 308.06 miles/hour
θ = 13.13° west of north.
Explanation:
Airplane speed = V₁ = 300 miles/hour
Wind speed = V₂ = 70 miles/hour
Resultant speed of the plane = V = ?
As airplane is trying to fly straight North and wind is blowing toward the west. So the angle between airplane velocity and wind velocity is 90°.
By Pythagoras Theorem
V =
V =
V = 308.06 miles/hour
θ = tan⁻¹(70/300)
θ = 13.13° west of north.
