Vi = Velocity initial = 35 m/s
Vf = Velocity final = 75 m/s
t = 5s
Equation:
Vf = Vi + at
65 = 35 + a(5)
30 = 5a
a = 6
Acceleration was 6 m/s^2
C. 6 m/s^2
It’s bad because the solar system controls the technology and affects your brain in a bad way
Assuming our "closed tube" is closed at only one end, then
<span> v = fλ = f*4L/n
</span><span> where "n" is the harmonic number. So
</span><span> L = nv / 4f = n*346m/s / 4*256Hz = n*0.38 m
</span> <span>Since the only option in your list that is an integer multiple of 0.38 m is 1.35 m
</span><span> I'd say that we're hearing the fourth harmonic.
answer is
</span><span>A. 1.35 m</span><span>
