Question

The answer is A)0.20 but can someone explain how to solve it plsss?!!

Answer 1

Step-by-step explanation:

The velocity of the wave is:

v = (9.0π rad/s) / (0.1π / cm)

v = 90 cm/s

v = 0.9 m/s

Velocity of a standing wave on a stretched string is:

v = √(T / (m/L))

0.9 m/s = √(0.081 N / (M / 2.0 m))

0.81 m²/s² = 0.081 N / (M / 2.0 m)

M / 2.0 m = 0.1 kg/m

M = 0.2 kg
