Archaeologist reconstructs the past by a study of the artefacts which they unearth such as stamps, coins, remains of buildings, clay, pots or burnt grains. Archaeologists excavate ancient sites. They try to find out about the lifespan of people by studying various unearthed artefacts such as- remains of houses, pots, jewellery, coins, agricultural tools, weighs etc. Archaeologists also try to find about the social or economic difference by studying the graves of people. If the burial consists of pottery and ornaments, it indicates that people during that time believed in after life.

Chhotu Upadhyay 6 years, 8 months ago

Cyclotron is a mechanical device used to accelerate charged to high kinetic energy in special vessel in which both electric and magnetic fields act perpendicular to eachother

K@Łp@N@ $Øđh!?? 6 years, 8 months ago

an apparatus in which charged atomic and subatomic particles are accelerated by an alternating electric field while following an outward spiral or circular path in a magnetic field.

Yogita Ingle 6 years, 8 months ago

Cyclotron is a device used to accelerate charged bodies to very high velocities (or high kinetic energies) using crossed (or mutually perpendicular) electric and magnetic fields
Cyclotron is based on the independency of frequency (of rotation of charged particle) on the energy (velocity) and radius (of revolution) of charged particle. The motion of charge , electric field, and the magnetic field are mutually perpendicular(θ= 90°), so:

f_c = 1/T = qB(sinθ)/(2πm) = qB/(2πm)

Do you find the title of lesson lost spring justified

Posted by Gurveer Singh 6 years, 8 months ago

CBSE > Class 12 > English Elective NCERT

1 answers

Sia ? 6 years, 8 months ago

Spring is the season of optimism and hope. It symbolizes life.But, unfortunately, millions of children in our country waste their childhood in rag picking and working in other hazardous industries. The joys of childhood, the vibrancy of spring is lost either in the garbage or in dingy cells with furnaces. The grinding poverty and traditions condemn these children to a life of exploitation. Children like Saheb and Mukesh have no spring in their life because of the poverty they have been born into . They see very little hope of escaping from their impoverished life of misery & deprivation. Moreover, years of mind-numbing toil have killed all initiative and the ability to dream. They are entangled in a spiral that moves from poverty to apathy to greed and to injustice. Since they don't enjoy the privileges of childhood that the children of affluent families enjoy, the poet considers these children whose spring (childhood) has been lost. Hence, the title 'Lost Spring' is justified.
