Answer:
B. 1.55 × 10³ m/s
Explanation:
f = 3.02 x 10^6 Hz
wavelength = 5.13 x 10^-4 m
v = ?
v = f*lamda
v = 3.02 x 10^6 × 5.13 x 10^-4
v = 1.55 × 10³ m/s
Longitudinal waves have movement in the direction of the wave energy.
Acceleration of an object is depended upon the net force acting open the object and the mass of the object
