Answer
- A and Bare the inputs and Y is the output of the given circuit. The left half of the given figure acts as the NOR Gate, while the right ha1f acts as the NOT Gate. This is shown in the following figure.
Hence, the output of the NOR Gate $=\overline{\text{A+B}}$
This will be the input for the NOT Gate. Its output wHI be ${\overline{\overline{A+B}}}=\text{A+B}$
$\therefore$ Y = A +B
Hence, this circuit functions as an OR Gate.
- A and B are the inputs and Y is the output of the given circuit. It can be observed from the following figure that the Inputs of the right half NOR Gate are the outputs of the two NOT Gates.
Hence, the output of the given circuit can be written as:
$ \text{Y}={\overline{\overline{\text{A}}+{\overline{\text{B}}}}}={\overline{\overline{\text{A}}\cdot{\overline{\text{B}}}}}=\text{A}\cdot\text{B}$
Hence, this circuit functions as an AND Gate.

In a typical Indian Bugghi (a luxury cart drawn by horses), a wooden plate is fixed on the rear on which one person can sit. A bugghi of mass 200kg is moving at a speed of 10km/h. As it overtakes a school boy walking at a speed of 4km/h, the boy sits on the wooden plate. If the mass of the boy is 25kg, what will be the new velocity of the bugghi?
Figure, shows an aluminium wire of length 60cm joined to a steel wire of length 80cm and stretched between two fixed supports. The tension produced is 40N. The cross-sectional area of the steel wire is 1.0mm2 and that of the aluminium wire is 3.0 mm2. What could be the minimum frequency of a tuning fork which can produce standing waves in the system with the joint as a node? The density of aluminium is 2.6g/cm3 and that of steel is 7.8g/cm3.
