The following figure shows a logic gate circuit with two inputs \(A\) and \(B\) and the output \(Y\). The voltage waveforms of \(A, B\) and \(Y\) are as given. The logic gate is
It is clear from the given logic circuit, that the output \(Y\) is low when both the inputs are high, otherwise it is high. Thus logic circuit is \(NAND\) gate.
A | B | Y |
---|---|---|
1 | 1 | 0 |
0 | 0 | 1 |
0 | 1 | 1 |
1 | 0 | 1 |
A sphere of radius R is cut from a larger solid sphere of radius 2R as shown in the figure. The ratio of the moment of inertia of the smaller sphere to that of the rest part of the sphere about the Y-axis is :
A bob of heavy mass \(m\) is suspended by a light string of length \(l\). The bob is given a horizontal velocity \(v_0\) as shown in figure. If the string gets slack at some point P making an angle \( \theta \) from the horizontal, the ratio of the speed \(v\) of the bob at point P to its initial speed \(v_0\) is :
Semiconductors are a crystalline solid materials, whose electrical conductivity lies between a conductor and an insulator. Semiconductors are mainly used in the manufacturing of electronic devices like capacitors, transistors, diodes, Integrated circuits, etc.
