Direction: Read the following passages carefully and answer the question that follows.
Regardless of how the state's feedback control law is designed, it is almost always necessary to implement it, using estimates of the state obtained from an observer. Hence, it is necessary to insure so that the desirable properties of the state feedback design do not vanish when the state estimate are used. It is proven in linear system theory courses that the command response is unaffected by the presence of the observer. However, the response to initial conditions will affect the system output. It is suggested that the observed poles should be made faster than the state feedback poles by an amount that depends upon the level of measurement noise. These conclusions are generally based upon transient time response properties of the system, and not on feedback properties such as robustness margins, We now present a procedure for tuning an observer so that, under appropriate conditions, the feedback properties of a state feedback design are recovered.
Q. On what basis suggestions are given?

Direction: Read the following passages carefully and answer the question that follows.
Seven-year -old Jim came home from the park without his new bicycle. "An old man and a little boy borrowed it. " he explained. "They are going to bring it back at four O'clock,". His parents were upset that he had given his expensive new bicycle, but were secretly proud of his kindness and faith. Came four O'clock, no bicycle. The parents were anxious. But at 4 :30, the door bell rang. and there stood a happy man and a boy , with the bicycle and a box of chocolates. Jim suddenly disappeared into his bedroom, and then came running out. ' All right , ' he said, after examining the bicycle. "You can have your watch back ! " .
Q. When jim came home without his bicycle, his parents?

Direction: Read the following passages carefully and answer the question that follows.
We know that gold and silver are elements. An element consists of atoms of only one kind, unlike water, which consists of both hydrogen and oxygen. Another element is radium. Radium is especially interesting, because it produces heat, When soil is carried by rivers down to the sea and falls to the bottom, it often carries radium in it. As more and more soil is washed down into the ocean. more and more radium is carried in it. There, as elsewhere, it constantly produces heat.
Q. Some heat on the ocean floor comes from?

Direction: Read the following passages carefully and answer the question that follows.
An iron or steel bridge swells (gets larger) when warmed by the Sun and shrink (gets smaller) when it becomes colder. Heat makes everything expand and cold makes everything contract. Cold is the absence of heat. Metals change their size when heated or cooled and this change is noticeable in a bridge that is made of iron or steel. The builder of a bridge must leave empty spaces for the metal to expand into. Have you noticed that concrete sidewalks have cracks every few feet ? These cracks provide space for the concrete to expand into when heated.

An ear of corn on a corn plant is protected by a husk and at the end of the ear, emerging from the husk, you can see a bunch of silk-like threads. What is the purpose of these threads ? Well, each thread is attached to a kernel of corn inside the husk and each kernel of corn, if it is fertilized by pollen, can become a seed that can grow into a new corn plant. How does pollen reach the kernel ? It travels through the silk-like thread, which is a hollow tube.

Why is it impossible to sink in the Dead Sea ? The reason is that, not only is the water in the Dead Sea heavier than ocean water and much heavier than fresh water. but it is also heavier than a person's body, when equal parts are measured. You can't sink in something that is heavier than you are. The reason for the heaviness is extreme saltiness. Are there materials that would sink in the Dead Sea ? Yes and I'II bet that you can think of some.
