Q9.
Ans:ABCD explain about opt C please!

Experts kindly solve it detail

find electric field at a distance of 30cm from a 3C charge

Average electric current in a conductor due to random thermal motion of electrons is (i) Zero (ii) Low (iii)High (iv) Depends on temperature of conductor

In the book in question 29, the answer is reported upto 2 significant digits while answer of   q 30 is reported upto 3 significant digits. why? how can one determine the number of significant digits to report to in these two questions? 

Experts can you answer this fast...

Q2.
Ans:B help pls conceptual issues here

A set of three coils having resistances 10 Ω, 12 Ω and 15 Ω are connected in parallel. This combination is connected in series with series combination of three coils of the same resistances. Calculate the total resistance and current through the circuit, if a battery of emf 4.1 Volt is

How many significant figures will ans be reported in q 29 and 30?
