The binary representation of hexadecimal number C3 is

The value of 2⁵ in octal system is

NAND and NOR gates are called 'Universal' gates primarily because:

The expression for exclusive NOR gate is

An AND gate has four inputs A, B, C, D. The input that produces an output 1 is

If the position of the resultant of two like parallel forces P and Q is unaltered, when the positions of P and Q are interchanged, then

A particle moves towards east from a point A to a point B at the rate of 4 km/h and then towards north from B to C at rate of 5 km/h. If AB = 12 km and BC = 5 km, then its average speed for its journey from A to C and resultant average velocity direct from A to C respectively are

With two forces acting at a point, the maximum effect is obtained when their resultant is 4N. If they act at right angles, then their resultant is 3N. Then the forces are

The difference in the variation of resistance with temperature in a metal and a semiconductor arises essentially due to the difference in the

Consider the following two statements A and B, and identify the correct answer.

A: During amplification, the frequency of the signal is increased.

B: The voltage gain is more in common base transistor amplifier than in common emitter transistor amplifier.

A transistor is operated in common emitter configuration at constant collector voltage Vc = 1.5 V such that a change in the base current from 100 µA to 150 µA produces a change in the collector current from 5 mA to 10 mA. The current gain (b) is
