Figure 25.11 shows the light rays leaving from all the points of the object. These rays after passing through the eyepiece pass through a small circular area. This is called the exit pupil or the eye ring R [see Fig. 25.11]. This is the best position where the eye should..

The gradual change in metallic character with the increase in atomic number is best illustrated in this group. Carbon and silicon arenonmetals of this group (silicon behaves as a semimetal in certain physical properties) whereas germanium is a metalloid, tin and lead are ..

Your mass and mass of your friend are 35 kg and 42 kg respectively. You are separated by 1 m. Calculate gravitational force between both of you. Solution : Here, m, = 35 kg, m2 = 42 kg, r = 1 m F = G ^^ = 6.67 X 10"11 X 35 V2 = 9.8 X 10"8 N r (1) Which is equal to the force exerted by 10 mi..

. Such a segregation is difficult, yet it can be achieved by two methods. Firstly, genealogies of various kindreds can be collected and analysed to find out which type of traits have persisted in their pedigrees. Secondly, all children can be first provided with idential nurture and, then, segregat..

Health means freedom from sickness, disease, anxiety (from social as well as psychological tensions). Good health is an essential condition for better purposeful living. A healthy person gives best to the society or community which he belongs to. WHO defined health as a state of complet..

(i) The light is totally reflected (100%) by the total reflecting prisms, while a mir- ror can reflect only 95% of the incident light, even with the best silvering. (ii) The reflecting properties of a prism is permanent and is not affected by tarnishing. But the silveri..

). Hydrogen passes out unabsorbed along with carbon monoxide. The carbon monoxide is removed by absorption in ammoniacal cuprous chloride solution. Traces of water vapour are removed by successively passing the gas through cooling coils (where the water vapour condenses) and then through a tower pa..

. I went to that class straight from the botany class which didn't help me any in understanding either subject. I used to get them mixed up. But not as mixed up as another student in my economics class who came there direct from a physics laboratory. He was a tackle on the football team, ..

AB. But on either side of AB, the image patch has a larger diameter. This patch of diameter AB is called the circle of least confusion. This is the position of the best possible image. The spherical aberration produced by a convex lens is positive and that of concave..

Remember, the evolution of "Man" as the wisest of all animal species is, till date, the highest achievement of "Organic Evolution". Only "Man" has acquired the capabilities of abstract thinking, logic and planning, syllabic speech and physical expression of emotions. Consequently..
