A reference is critical because it determines how much motion has occurred. You can't determine how much an objected has moved if you don't know where it came from.
Answer:
0.076 kg
Explanation:
The force created by gravity can be found using mass x (9.8 m/s^2).
mg=0.750 N
m(9.8) = 0.750
Multiply both sides by 9.8: m = 0.076 kg
Assuming an ideal gas, the speed of sound depends on temperature
only. Air is almost an ideal gas.
Assuming the temperature of 25°C in a "standard atmosphere", the
density of air is 1.1644 kg/m3, and the speed of sound is 346.13 m/s.
The velocity can't be specified, since the question gives no information
regarding the direction of the sound.
