A displacement : acceleration B force : kinetic energy C momentum : velocity D power : speed 16 Which of the following could be measured in the same units as force? A energy / distance B energy x distance C energy / time D momentum x distance 17 The notation µs is used as an abbreviation for a certain unit of time. When measuring the sound level from a specific source of sound (not ambient noise), the sound level drops at the rate of 6 dB per doubling of distance. The sound level L p2 at a distance r₂ can be determined using the following formula: L p2 = L p1 + 20 log 10 (r₁/r₂) dB, Where L p1 is the sound level measured at the distance r₁. This ...
