10 = 1
11 = 0

A half adder is a type of adder, an electronic circuit that performs the addition of numbers.
The half adder is able to add two single binary digits and provide the output plus a carry value.
The half adder circuit has two inputs: A and B, which add two input digits and generate a carry and sum.

Hooke’s law is valid only within the elastic limit. In the elastic limit the strain varies proportionally with the stress applied where the law is valid.

The plane at which the shear stress is zero is termed as the principal plane.

The potential barrier in the pn junction is the barrier which does not allow charge flow across the junction normally. … This resistance to the flow of charge is known as barrier potential. Barrier potential of a silicon diode at room temperature is 0.7V. Barrier potential of a germanium diode is 0.3V.

Ripple factor is defined as the ratio of the effective value of AC components to the average DC value. It is 0.48 for full wave rectifier

Then a single stage Common Emitter Amplifier is also an ?Inverting Amplifier? as an increase in Base voltage causes a decrease in Vout and a decrease in Base voltage produces an increase in Vout. In other words the output signal is 180 degree out-of-phase with the input signal.

Quality factor and frequency of oscillation of a colpits oscillator are directly proportional. Thus when Q decreases in colpits oscillator, the frequency of oscillation also decreases.

The ideal op amp is an amplifier with infinite input impedance, infinite open-loop gain, zero output impedance, infinite bandwidth, and zero noise.
It has positive and negative inputs which allow circuits that use feedback to achieve a wide range of functions.
Therefore the correct option is D.

8051 microcontroller IC has 40 pins.
