As naturally we all studying this topic on the 10 class of this chapter and can i knows some natural questions on ours ongoing daily life on this chapter’s basis.
On at technically and mechanically can i brought some questions on this topic.
Ow , please reply back to me onto your honours!
these mcq for sec A only
Can electromagnetism are able to harm our body by mixing with the radiation as well as harmful radiation.
Can electromagnetism are able to harm our body by mixing with the radiation as well as harmful radiation.
On going with under the water of a pond and another one who supplied microwave then what type of affection occur on ourselves.
How radiation affects our lungs , heart and repairable system!
On at home in what amount of damage did ours body by these radiations !
Likewise ours mobile phones wifi , router’s radiation etc.
