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:
216480000 fathoms
Explanation:
1 fathom = 6 feet
Distance from Earth to the Moon = 246000 miles
Converting to feet
1 mile = 5280 feet
246000 miles = 1298880000 feet
Convert to fathom
So, the distance between Earth and Moon is 216480000 fathoms
