Answer:
F = 0.179 N
Explanation:
given,
length of the rod = 0.759 m
mass of the rod = 1.03 kg
force = ?
initial angular speed = 0 rad/s
final angular speed = 6.87 rad/s
time interval = 9.95 s
the angular acceleration



moment inertial of the rod

torque produced by the rod τ = I α
torque is also equal to τ = F L
now,
F L = I α


F = 0.179 N
Answer:
I think it might be 8kg grams because it is bigger
Answer:
912 Hz
Explanation:
Third harmonic multiplies the frequency by 3. Harmonics are waves that operate at a frequency that is an integer (whole-number) multiple of the fundamental frequency.
