Answer:

Explanation:
given,
number of cycle complete (f) = 116 cycles per minute
wavelength observed at 11 m in 1.5 m.


v = 7.33 m/s




The wavelength of the wave is equal to 
Compared with the amount of current in the filament of a lamp, the amount of current in the connecting wire is
D. the same.
As per the rule, the amount of current in devices connected in series is equal. here in the given situation , the wire is in series with the filament. that is the reason that the current in filament and wire is same.
hence the correct choice is D)
