ICSE − Q & A

1.why is voltmeter connected in parallel
2.what happens when electric bell is supplied with ac current

In the 2016 edition, gear ratio is wrong right?
It should be NB/NA.
Then , is the gain in torque also wrong? And the gain in speed? Should they be changed?

Pls give relations between wavelength, refractive index, speed, deviation,

Can anyone  say me what happens  if a radioactive  substance is oxidised

pg 164 question 27(IN CONCISE)
Hey,  in that question why are they sayin that since the length of air column in B is 3 times that of D therefore resonance is taking place because A and C are 4 and 2 times that of D?

For the heating curve of water, do we also draw the part after vaporisation?
