MCQ
Which of the following diagrams does not represent a streamline flow?
  • A
  • B
  • C

Answer

Correct option: D.
​​​​​​In streamlined flow the velocity of fluid at any given point remains constant (at a particular line) across any cross-sectional area. Hence is streamline flow layers do not cross each other. Hence option (d) is not streamline.

As shown in the figure, in an experiment to determine Young's modulus of a wire, the extension-load curve is plotted. The curve is a straight line passing through the origin and makes an angle of $45^{\circ}$ with the load axis. The length of wire is $62.8\,cm$ and its diameter is $4\,mm$. The Young's modulus is found to be $x \times$ $10^4\,Nm ^{-2}$. The value of $x$ is
