(ii) All political systems do not perform the same functions. (iii) All political systems are not multi-functional. (iv) All political systems are mixed systems in the cultural sense.

Below stated are some of the statements about the Alternating current. You need to identify which of the following is incorrect, 1. DC power is far more powerful than AC power. The efficiency and power to size characteristics of DC motors and apparatuses are increased. Lighting by DC (LED) is 75% more efficient than lighting from incandescence. 2. A comparatively high voltage alternating current may be generated and easily raised and dropped by the static equipment known as the transformer, which makes electrical energy transmission and distribution economical, 3. Initial costs and maintenance of the AC motor are less expensive since it has no switch and is less powerful than the DC motor for constant working speed, hence it is desired to create power as alternating current. 4. The great efficiency of transmission in ac makes electric power generation cost-effective, Produced in huge quantities in one station and distributed throughout a vast area.
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?
Which of the following is/are true about dipole? (1) The unit of electric dipole moment is coulomb meter (2) The net charge of the electric dipole is zero (3) The net electric field due to an electric dipole is nonzero. (4) Point diploe is the diploe with a small value of the charge.
