A transparent square sheet shown above is folded along the dotted line. The folded sheet will look like \(\underline{\hspace{2cm}}\).





Step 1: Identify the fold line.
The sheet is folded along the vertical dotted line, meaning the right half folds onto the left half. Because the sheet is transparent, the drawing on the right side will appear as a mirror image on the left after folding.
Step 2: Visualize the reflection.
The original figure contains a vertical line at the center and two slanted lines attached to it. When reflected across the dotted line, the right-side slanted line flips horizontally, forming a symmetric "< >" shape.
Step 3: Compare with given options.
Option (C) correctly shows the mirrored shape after folding, where the two slanted lines form a symmetric pair around the central vertical line.
Final Answer: (C)
A square paper, shown in figure (I), is folded along the dotted lines as shown in figures (II) and (III). Then a few cuts are made as shown in figure (IV). Which one of the following patterns will be obtained when the paper is unfolded?

Given an open-loop transfer function \(GH = \frac{100}{s}(s+100)\) for a unity feedback system with a unit step input \(r(t)=u(t)\), determine the rise time \(t_r\).
Consider a linear time-invariant system represented by the state-space equation: \[ \dot{x} = \begin{bmatrix} a & b -a & 0 \end{bmatrix} x + \begin{bmatrix} 1 0 \end{bmatrix} u \] The closed-loop poles of the system are located at \(-2 \pm j3\). The value of the parameter \(b\) is:
