THE ANSWER IS 16 ohms or however its spelled
Radial fractures tend to occur first when a pane of glass is struck.
Answer: Option A
<u>Explanation:</u>
There is a slight difference between radial and concentric fractures and as radial fractures are formed which extends outwards in a radial manner from the point where the glass is struck.
Whereas concentric fractures are circular in pattern and they terminate long before radial crack. Also when a bullet is fired from a gun, a similar reaction is observed as it gets struck on the surface and fractures are formed in the same pattern.
<u>Answer</u>:
The stream flowing at a speed of 
<u>Explanation</u>:
Given:
Distance = 2km (both in upstream and downstream)
The speed in still water be x km/hr.
The speed in upstream = 4-x
Speed in downstream = 4+x
Solution:
We know that, Speed = distance/time
So, Time = distance/speed
Therefore,




By cancelling 2 on both sides,




Result:
Thus the speed of the stream is
