Consider the following opinions regarding the advantage and disadvantage of a Mealy model: 1. Advantage: Less number of states (hence less hardware) Disadvantage: Input transients are directly conveyed to the output 2. Advantage: Output remains stable over the entire clock period. Disadvantage: Input transients persist for a long duration at the output. Which of the above is/are correct?
Based on the given para, answer the following question. Sensitivity considerations often are important in the design of Control Systems. Because all physical elements have properties that change with environment and age, we cannot always consider the parameters of the Control System to be completely stationary over the entire operating life of the system. For instance, the winding resistance of an electric motor changes as the temperature of the motor rises during operation. Control systems with electric components may not operate normally when first turned on because of the still-changing system parameters during warmup. This phenomenon is sometimes called “morning sickness”. Most duplicating machines have a warmup period during which time operation is blocked out when first turn on. A good Control System should be: (a) Very sensitive to parameter variations (b) Insensitive to parameter variations (c) Insensitive to input commands (d) Sensitive to input commands Which of the above are correct?

Read the given passage/argument and answer the question that follow it. Govt of India has reconfirmed their plans to go full ballistic for electric cars. An announcement which will make Elon Musk and patrons of electric vehicles super happy, India plans to allow the sale of only electric cars by 2030, which is just 12 years away. This means that petrol/diesel cars won’t be allowed on the road after 2030. This is a massive, powerful endorsement of electric, green technology, and can change transportation industry forever.  Which of the following argument can be made from above passage?
Why do vehicle tires experience a loss of traction, and slip during a rainy day on a wet road? a) Because during rainy day efficiency of the engine drops effectively b) Because during rainy day roads are normally wet and this reduces friction between car and vehicle. c) Because during rainy day roads are normally wet and this increases friction between car and vehicle and hence, we experience loss of traction and vehicle slips.
