Crystal watches are the fastest. your question is highly field specific

4.Electricity does not move around wire but through a field around a wire?
yes

5.What is Pitch?

go to wikipedia

8.The fruit without seed is called?

banana, process is called parthenocarpy/virgin production

10.The half life of a radioactive element is 8 days?How long will it take to reduce from 10mg?

complete question: 10.The half life of a radioactive element is 8 days?How long will it take to reduce from 10mg to 5 mg?
answer: not possible physically, as the chemical/internal nature of element is changed, mass remains same


11: antenna

12: cloning, genetic engineering

13: search Valine on net

14: b

[adroit.jrk]

2.Clocks which moves with the velocities comparable with the velocity of light run
c.Equal to the velocity of light

10.complete question: 10.The half life of a radioactive element is 8 days?How long will it take to reduce from 10mg to 5 mg?
Ans: 8 days (because it will reduce from 10mg to 5mg, it means 5mg is half life.)

11.Television signals are converted into light signals by ?
Ans: It is RTC, antenna just receives signals and it is the function of RTC to convert the signal into Light signals..
