Answer:
Explanation:
Given that:
Efficiency = 2.06 % = 0.0206
The intensity level of sound is given by the formula:
Taking their exponential; we have :
Replacing our values; we have:
Power Output;
The power output that is required to produce a 89.6 dB sound intensity level for a 13.0 cm diameter speaker that has an efficiency of 2.06% is;
Therefore, The power output that is required to produce a 89.6 dB sound intensity level for a 13.0 cm diameter speaker that has an efficiency of 2.06% is
Answer:
AN electric current is required for an electric charge
Explanation:
Answer:
Up And Down
Explanation:
In this case, the particles of the medium move parallel to the direction that the pulse moves. This type of wave is a longitudinal wave. Longitudinal waves are always characterized by particle motion being parallel to wave motion.
