You have:
A1= 0.15 m²
A2=6.0 m²
F1=130.0 N
To solve this problem you must use the pressure formula, as below:
P1=P2
F1/A1=F2/A2
Then, you have:
m2=A2xF1/A1xg
g=9.81 m/s² (This is the acceleration of gravity)
When you substitute the values in m2=A2xF1/A1xg, you obtain:
m2=(0.60 m² x 130.0 N)/(0.15 m² x 9.81 m/s²)
The answer is:
m2=530 Kg
Answer:
<em>The volume of the feathers in ft³ = 16 ft³</em>
Explanation:
Density: This can be defined as the ratio of mass of a body to the corresponding volume of that body. The S.I unit of Density is kg/m³
Mathematically it can be expressed as,
D = m/v ................................... Equation 1
making v the subject of the equation above,
v = m/D ............................. Equation 2
Where D = Density of the feathers, m = mass of the feathers, v = volume of the feathers.
Given: D = 0.50 lbs/ft³, m = 8.0 lbs.
Substituting into equation 2
v = 8/0.5
v = 16 ft³
<em>Thus the volume of the feathers in ft³ = 16 ft³</em>
Answer:2200 hz
Explanation:
speed=242m/s
Distance between crest is there wavelength=0.11m
Frequency=speed ➗ wavelength
Frequency=242 ➗ 0.11
Frequency=2200
Frequency=2200 hz
