1. Q.1 When we accept the evidence of our unaided eyes and describe the Sun as a yellow star, we have summed up the most important single fact about it-at this moment in time.

It appears probable, however, that sunlight will be the color we know for only a negligibly small part of the Sun’s history. Stars, like individuals, age and change. As we look out into space, We see around us stars at all stages of evolution. There are faint blood-red dwarfs so cool that their surface temperature is a mere 4,000 degrees Fahrenheit, there are searing ghosts blazing at 100, 000 degrees Fahrenheit and almost too hot to be seen, for the great part of their radiation is in the invisible ultraviolet range. Obviously, the “daylight” produced by any star depends on its temperature; today(and for ages to come) our Sun is at about 10,000 degrees Fahrenheit, and this means that most of the Sun’s light is concentrated in the yellow band of the spectrum, falling slowly in intensity toward both the longer and shorter light waves.

That yellow “hump” will shift as the Sun evolves, and the light of day will change accordingly. It is natural to assume that as the Sun grows older, and uses up its hydrogen fuel which it is now doing at the spanking rate of half a billion tons a second- it will become steadily colder and redder.

2. Q.2 Forces other than damaging winds are also at work inside tornadoes. Sometimes, as the writhing, twisting funnel passes over a house, the walls and ceiling burst apart as if a bomb had gone off inside. This explosion is caused by the low air pressure at the center of a tornado.

The pressure at the center of a tornado is usually 13 pounds per square inch. However, inside the house, the air pressure is normal, about 15 pounds per square inch. The difference of 2 pounds per square inch between the inside and outside pressure may not seem like much. But suppose a tornado funnel passes over a small building that measures 20 by 10 by 10 feet. On each square inch of the building, there is 2 pounds of pressure from the inside that is not balanced by air pressure outside the building. On the ceiling, that adds up to an unbalanced pressure of 57, 600 pounds. The pressure on the four walls adds up to 172,800 pounds.

If windows are open in the building, some of the inside air will rush out through them. This will balance the pressure inside and outside the building. But if the windows are shut tightly, the enormous inside pressure may cause the building to burst.

Unfortunately, heavy rain and hail often occur in thunderstorms that later produce tornadoes. So people frequently shut all windows to protect their property. This may cause far worse damage later. For the same reason, tornado cellars must have an air vent. Otherwise, the cellar door might be blown out when a tornado passes over it.

3. Q.3 The crisis begins in the womb with unplanned parenthood. Women with unplanned pregnancies are less likely to seek prenatal care. In the U.S. 80% of teenage pregnancies and 56% of all pregnancies are unplanned. The problems continue after birth where unplanned pregnancies and unstable partnerships often go hand in hand. Since 1950, the number of single-parent families has nearly tripled. More than 25 percent of all births today are to unmarried mothers. As the number of single parent families grows and more women enter the workforce, infants and toddlers are increasingly in the care of people other than their parents. Most disturbingly, recent statistics show that American parents are increasingly neglecting or abusing their children. In only four years from 1987-1991, the number of children in foster care increased by over 50 percent. Babies under the age of one are the fastest growing category of children entering foster care. The crisis affects children under the age of three most severely, the report says. Yet, it is this period from infancy through preschool years that sets the stage for a child’s future.

Ques 3. What can be the possible reasons for the increasing neglect and abuse of children?

4. Q.4.Early Rising-The great advantage of early rising is the head start it gives us in our day’s work. The early riser has done a large amount of hard work before other men even get out of bed. In the early morning, the mind is fresh, and there are few sounds or other distractions. In many cases the early riser also finds time to take some exercise in the fresh morning air. By beginning so early, he knows that he has plenty of time to do thoroughly all the work he can be expected to do. All his work having been finished in good time, he has a long interval of rest in the evening before the timely hour when he goes to bed. After a sound night’s rest he rises early next morning in good health and spirits for the labours of a new day

Late Rising-The person who lies in bed late, if he wishes to do a full day’s work, goes on working to a corresponding late hour and denies himself the hour or two of evening exercise that he ought to take for the benefit of his health. Very late in the night is he ready for sleep.

5. Q.5 Exposure to high levels of noise can cause permanent hearing loss. Neither surgery nor a hearing aid can help correct this type of hearing loss. Short-term exposure to loud noise can also cause a temporary change in hearing (your ears may feel stuffed up) or a ringing in your ears (tinnitus). These short-term problems may go away within a few minutes or hours after leaving the noise. However, repeated exposures to loud noise can lead to permanent tinnitus and/or hearing loss.

Loud noise can create physical and psychological stress, reduce productivity, interfere with communication and concentration, and contribute to workplace accidents and injuries by making it difficult to hear warning signals. The effects of noise-induced hearing loss can be profound, limiting your ability to hear high-frequency sounds, understand speech, and seriously impairing your ability to communicate.

When sound waves enter the outer ear, the vibrations impact the ear drum and are transmitted to the middle and inner ear. In the middle ear, three small bones called the malleus (or hammer), the incus (or anvil), and the stapes (or stirrup) amplify and transmit the vibrations generated by the sound to the inner ear. The inner ear contains a snail-like structure called Cochlea which is filled with fluid and lined with cells with very fine hairs. These microscopic hairs move with the vibrations and convert the sound waves into nerve impulses–the result is the sounds we hear. Exposure to loud noise can destroy these hair cells and cause hearing loss!
