Because the electrons collide with the particles inside the conductor so are therefore slowed down seen as current is the rate of flow of electrons
Answer:
Explanation:
given,
frequency of tuba.f = 64 Hz
Speed of train approaching, v = 8.50 m/s
beat frequency = ?
using Doppler's effect formula
v_s is the velocity of the source
v is the speed of sound, v = 340 m/s
now,
f' = 65.64 Hz
now, beat frequency is equal to
hence, beat frequency is equal to 1.64 Hz
