Answer:
For pipes that play low-frequency notes, the advantage of using a tube which is open at both ends is that it produces sound whose wavelength is just twice the length of the tube but a tube which is open at one end and closed at the other produces sound with a wavelength equal to four times the length of the tube.
Therefore the tube which is open at both ends more suitable for low frequency note.

Answer:
6844.5 m/s.
Explanation:
To get the speed of the satellite, the centripetal force on it must be enough to change its direction. This therefore means that the centripetal force must be equal to the gravitational force.
Formula for centripetal force is;
F_c = mv²/r
Formula for gravitational force is:
F_g = GmM/r²
Thus;
mv²/r = GmM/r²
m is the mass of the satellite and M is mass of the earth.
Making v the subject, we have;
v = √(GM/r)
We are given;
G = 6.67 × 10^(-11) m/kg²
M = 5.97 × 10^(24) kg
r = 8500 km = 8500000
Thus;
v = √((6.67 × 10^(-11) × (5.97 × 10^(24)) /8500000) = 6844.5 m/s.
