Initially its moving with tail wind so here the speed of wind will support the motion of the plane
so we can say



now when its moving with head wind we can say that wind is opposite to the motion of the plane



now by using above two equations we can find speed of palne as well as speed of wind


Answer:
silicon is the second most abundant element in Earth’s crust. It is found in the sun and stars; and in clay which is used to make pottery.
Explanation:
<span>(a) E = ½ Q²/C, so ..
(b) E(max) = ½Li² (i=current), so .</span>
Due to the fact that for every action there is an equal reaction for every turn on the screw the screw will exert energy equal to the amount you gave
The answer is focal point.
The focal length is the distance from the lens (or mirror) to the focal point. The focal point is <span>the point at which rays of light converge.</span>
