Power = Work/Time
Convert 5 min to seconds and divide 2150J by that number.
Answer:
The intensity in 10-3 W/m2 at 39.3 m is
Explanation:
Given Data:
frequency=1,054 Hz
intensity=6.429 mW/m^2
distance=7.945 m.
Required:
intensity in 10^-3 W/m^2 at 39.3 m=?
Solution:
Intensity at distance r from point source which is emitting sound waves of power P is given by the following formula:
Intensity=I=
Where:
P is the power
r is the distance
The intensity in 10^-3 W/m2 at 39.3 m is
0 degrees celcius
32 degrees fahrenheit
273.15 degrees kelvin
Answer:
the net force or resultant force
50 degrees because the would most likely equal out
