Preeti Dabral 2 years, 11 months ago

I – Sometimes I find a rupee in the garbage. The first part tells the writer’s impressions about the life of the poor rag pickers. The rag pickers have migrated from Dhaka and found a settlement in Seemapuri. Their fields and homes had been swept away by storms. They had come to the big city to find a living. They are poor. The writer watches Saheb every morning scrounging for “gold” in her neighbourhood. Garbage is a means of survival for the elders and for the children it is something wrapped in wonder. The children come across a coin or two from it. These people have desires and ambitions, but they do not know the way to achieve them. There are quite a few things that are unreachable to them, namely shoes, tennis and the like. Later Saheb joins a tea stall where he could earn 800 Rupees and all the meals. The job has taken away his freedom.

II – I want to drive a car.

The second part deals with the life of Mukesh, who belongs to the family of Bangle-makers. Firozabad is best known for its glass-blowing industry. Nearly 20,000 children are engaged in this business and the law that forbids child labour is not known here. The living condition and the working environment is a woeful tale. Life in dingy cells and working close to hot furnaces make these children blind when they step into the adulthood. Weighed down by the debt, they can neither think nor find a way to come of out of this trap. The politicians, middlemen, policemen and bureaucrats will all obstruct their way of progress. The women in the household consider it as their fate and just follow the tradition. Mukesh is different from the rest of the folk there. He dreams to become a motor mechanic. The garage is far away from his house but he shall walk. comes across Mukesh in Firozabad.

Formic acid is stronger than acetic acid.

Anjan Karthi 2 years, 11 months ago

The main reason for stability of carboxylate anion formed by acidic property of carboxylic acids is resonance. But, even under such stability there does exist a possibility that the carboxylic carbon have some residual deficit of negative charge (not actually positive charge) , and this may be caused by the +I effect of alkyl groups connected to the carbon. But, since formic acid has no alkyl group connected to the acid group, it is the stronger than acetic acid.

A small candle 2.5 cm in size is placed at 27 in front of a concave mirrir of radius of curvature 36 cm at what distance from the mirror should a screen be placed in a order to obtain a sharp image ? Describe the nature and size of the image if the candle is moved closer to the mirror , how would the screen have to be moved ?

Anjan Karthi 2 years, 11 months ago

h = 2.5 cm. u = - 27 cm. R = 2f = - 36 cm. Therefore, according to mirror formula, 1/f = 1/v + 1/u. 1/v = 1/f - 1/u = 1/18 - 1/27 = - 9 / 18 × 27 = - 1 / 54. v = - 54 cm. Magnification m = -v/u = 54/-27 = - 2 = h'/h. h' = mh = - 2 × 2.5 = -5 cm. So, the image is real, inverted and enlarged and is formed at a distance greater than R in front of the mirror. If the candle is brought closer to the mirror, then the screen should be moved far away from the mirror.
