1what happens when washing soda crystal is exposed to air ?is it looses 9 water of crystalisation
2what is white light
3why does ordinary soap cause irritation
4How will you explain – the phenomena of electromagnetic induction in one – coil when current passing through a neighboring coil increase or decrease?(did not understand question)
5Name two types of drugs used in chemical method of population control?
6What is the composition of nervous system in higher vertebrates?

1) Yes, it looses 9 water of crystallisation.
2) Any light which produces a spectrum similar to that of sunlight is called as white light.
3) Donno
4) I don't understand question.
5) Donno
6) It comprises of 3 nervous systems: Central Nervous System (Brain and Spinal Cord), Autonomous Nervous System (Cranial and Spinal Nerves) and Peripheral Nervous System (Sympathetic and Para-Sympathetic).

1) bcappu is right
2> i think white light is tht light which when passed through a prism disperses 7 colors (rainbow colors)
3>its basic character (i think)
4>i think tht question means like this-

there is this coil and there is a coil nearby through which current is flowing. and they hv asked wt will be the phenomena of electromagnetic in the first coil..
so... when current is flowing in the second coil it will produce magnetic effect on the first coil... which will produce current in the first coil...

5>it is those pills taken to avoid pregnancy.

6>i think bcappu is right

2) That is the same answer aparnapm, I had stated

Sunlight produces a spectrum which produces 7 colours ( that of a rainbow) and any light producing a similar spectrum of that of sunlight (rainbow) is called as white light.

yea... true....

thx people ..bc appu the peripheral nervous system is cranial nerves and spinal nerves and not autonomous system
3 i am not too sure
4not too sure also
5 they are askin for 2 drugs

since i got these from a guess paper i think many of them might not be there for us like the 2 drugs thing

yeh.. I interchanged the peripheral and autonomous nervous system. Sorry :mrgreen:
