That would be a decomposer
Hope this helps!
Initial speed(u)=0m/s
Final speed(v)= 27m/s
Time(t)=7.6s
Use the equation of motion: v = u + at
27 = 0 + a(7.6)
27/7.6 = a
a = 3.55 m/s^2 (3 s.f)
Answer:
The average distance is 999.936 light years.
Solution:
As per the question:
Ours is the Milky Way Galaxy with the diameter:
D = 1,00,000 ly
Radius, R =
Now,
A =
The area to each civilization, A' is:
A' =
The radius of each area of civilization, r:
Thus the average separation distance between civilizations is given as:
2r =
"forces between molecules"
less than 20 Hz
The frequency of subsonic sound is less than 20 Hz
subsonic sound refers to a sound which has a wave that travels slower than the speed of sound.
- frequency of audible sound: 20 Hz to 20,000 Hz
<u>Thus </u>subsonic sound < 20 Hz
