what tremor means?
WHAT IS LIGHTNING CONDUCTOR? WRITE ITS USES?
how does a thunderstorm occur?
What are plate tectonics???
how things get charged by rubbing on hair? do hair have electricity in it?
When a positively charged body is brought near an uncharged metal rod, the part of the rod near the charged body acquires a negative charge, and the far side a positive charge. Can you say why this happens? Remember that in a body negative charge are mobile whereas positive charge are fixed.
What is the Bermuda Triangle???
what is earthing?
why isn't other scales used widely?

please send answer fast because i have to submit my copy on 20/12/12
wood is a bad conductor. then why shouldn't we take shelter under a big tree?
is the no. of electron and proton equal in every atoms
explain the working of a lightning conductor?
why are taller buildings in greater danger of being struck by lightning?
What Is The Difference Between
EMI And EMF
can an electroscope measure and detect the nature of charge whether it is positive or negative if yes then how?
explain in what way is lightning useful ?
which part is crust ? please give a picture!
In earthquake prone areas ,houses are usually built with wood .Why?
what is a lightning conductor
what is convention ?

Q1) state 2 uses of electroscope
Q2) TV screens become dusty very soon.why?
Q3) why is the upper end of the lightning conductor is made into a trishul?
(respected experts pls fast ai have a test on monday)
Construction engineers and architects need to be familiar with earthquakes. Why?
how does electrical discharge occur in clouds ????????????????????
Explain about electrostatic induction?
what are tectonic plates?
please justify the statement "It might be dangerous to raise an umbrella in a storm"
how can you identify whether an object carries positive or negative charge
THE CHARGE CAN BE EITHER POSITIVE OR NEGATIVE? THAT IS, IN THE VEDIO THEY SHOWED POSITIVE BUT IF NEGATIVE CHARGE COMES WILL IT REPEL?
Raju was able to charge a plastic comb by rubbing it in his dry hair, but not a metal comb. Why?
explain how an earthquake occurs
how lightning occurs between two clouds during a storm?
whena positively charged body is brought near an uncharged metal rod the part of the rod near the charged body acquires a negative charge, and the far side a positive charge. Can you say why this happens ? Remember that ibn a body, negative charge are mobile where as positive charge are fixed.
what is difference between conduction and induction???
WHAT IS EARTHING?
A crackling sound is heard by taking of a sweater during winter.why?
Explain - (i) charging by induction (ii) charging by conduction (iii) charging by friction.
explain the effects of deforestation of forest soil.
as we knw upper region of clouds aquire positive charge whereas lower regions acquire negative charge. then how can lightning occur if all clouds are charged in the same way as lightning occurs between unlike charges??????????
plz answer quickly i will give u 5 thumbzzzzz up ,,,,,,,,,,,,,, plz its urgent
what are the causes of over utilisation of natural resources?
WHY DID THE SPARKS COME WHEN WE RUB TWO STONES TOGETHER??
how does lightning take place between the clouds?
