You strike a tuning fork and find that the first harmonic/fundamental resonance is produced when the air column length or height or depth
at 0.166 m. If the speed of sound is 340 m/s, what is the frequency of sound wave produced by the tuning fork in Hz?

an electric circuit

magnets not strong enough

explanation:

electrical potential energy =0.072 j

explanation:

electrical potential energy is given by

u= q δv

q= charge=6 c

δv= potential difference and is given by

δv= e d

e= electric field

d= distance=5 mm=0.005 m

δv=2.4 (0.005)=0.012 v

now electric potential energy= u= q δv

u=6 (0.012)

u=0.072 j
