IIT Hyderabad has announced the launch of a full-fledged bachelor's programme in Artificial Intelligence technology.

The explanation for the given correct answer is that gas-refrigeration cycles typically have lower COP (Coefficient of Performance) compared to vapor compression cycles for the same capacity. This is because gas-refrigeration cycles operate on the principle of gas absorption or adsorption, which generally requires more energy input and is less efficient than the vapor compression cycle. Vapor compression cycles, on the other hand, use a compressor to increase the pressure and temperature of the refrigerant, resulting in a higher COP. Therefore, the COP of a gas-refrigeration cycle is lower than that of a vapor compression cycle for the same cooling capacity.

To add the numbers 97310 and 3910 using BCD (Binary Coded Decimal) adders, three BCD adders would be required. BCD adders are used to perform arithmetic operations on BCD numbers, where each digit of a number is represented by a binary code. Since both numbers have a total of 5 digits, three BCD adders would be sufficient to add them. Each BCD adder can handle up to two BCD digits, so three adders can handle a total of six digits, which is enough to accommodate the two numbers being added.

A ring laser type gyroscope operates based on the Sagnac principle. The Sagnac effect is a phenomenon in which the phase difference between two counter-propagating beams of light is measured to determine the rotation rate of the gyroscope. This effect is caused by the rotation of the gyroscope itself, resulting in a phase shift in the light beams. By measuring this phase shift, the gyroscope can accurately detect and measure rotational motion.

When the rate of evaporation of water is zero, it means that no water molecules are transitioning from the liquid phase to the gas phase. This indicates that the air is holding the maximum amount of water vapor it can at that temperature, resulting in saturation. Therefore, the relative humidity of the air is 100%, as it is fully saturated with water vapor.

The code declares a union named "test" with three members: an integer, a float, and a character. It then dynamically allocates memory for a variable of type "test" using malloc(). The code assigns a value of 10.10f to the float member of the union. Finally, it prints the value of the float member using printf(). Since the float member was assigned a value of 10.10f, the output will be "10.100000000".

The primary interactive method of communication used by humans is speaking. This is because speaking allows individuals to convey their thoughts, ideas, and emotions through the use of spoken language. It is a fundamental form of communication that enables people to engage in conversations, express themselves, and understand one another. While reading and writing are also important forms of communication, they are not considered as primary interactive methods since they involve a more individualistic and non-verbal approach.

In idling condition, the engine is running at a low speed or is not moving at all. During this condition, the air-fuel mixture needs to be rich, meaning that there is more fuel relative to the amount of air. This is because a richer mixture helps to ensure a smooth and stable idle, providing enough fuel for combustion and preventing stalling. A lean mixture, on the other hand, would have less fuel and more air, which could result in a rough idle or even engine stalling. Therefore, the correct answer is rich.

In this case, the circuit is responding to a specific set of signals and producing a related digital signal output, which aligns with the definition of an encoder. Therefore, the correct answer is Encoder.

Default access is the most restrictive access level that allows a class to have access to members of another class in the same package. Default access means that the members are only accessible within the same package, and not from outside the package. This ensures that the members are not accessible to classes in other packages, providing a level of encapsulation and restricting access to the package level.
