The coil of a galvanometer has so tuons and its
resistance is 102. It is replaced by a coil having
100 tums
and resistance son
find the factor
by which
the
curdent and voltage sensitivities
change.
Hea,
Ni so turns
8= 102​

It would be c hope this out

Sounds propagates through some kind of medium. usually it's air, but it goes just as well through solid objects like walls, windows etc. a soundwave will compress the (air)molecules in front of it, and if this increased density wave hits your ears, you register it as sound. solid objects like walls are a lot denser than air, this means that they will damp a wave, but also carry it easier.
