azamat
<h3><u>Answer</u> :</h3>

<u>Focal length of convex lens is taken positive.</u>

:\implies\sf\:\dfrac{1}{v}-\dfrac{1}{u}=\dfrac{1}{f}

:\implies\sf\:\dfrac{1}{v}-\dfrac{1}{(-30)}=\dfrac{1}{20}

:\implies\sf\:\dfrac{1}{v}=\dfrac{1}{20}-\dfrac{1}{30}

:\implies\sf\:\dfrac{1}{v}=\dfrac{3-2}{60}

If you walk along a log floating on a lake why does the log move in the opposite direction?
aivan3 [116]

<em>HERE'S</em><em> </em><em>YOUR</em><em> </em><em>ANSWER</em><em>: </em>

•Since the log is stationary and you are moving beside the log, it seems to move in the opposite direction from your point of view, because from your perspective u are stationary and the log is moving. If you were to stop moving the log would also stop moving.
