To find the mass of benzene, we must first solve for the volume of benzene inside the cylindrical drum. To calculate the volume of the partially filled cylindrical drum, refer to the working formula below:
Volume = L {(R^2)cos-1[(R-H)/R)] - (R-H)(2RH-H^2)^0.5}
Where:
L = length of the drum = 2 meters
R = radius of the drum = 4 meters
H = height of the liquid = 0.85 meter
substituting the given to the formula, we get
Volume = 5.087 m3
To solve for the mass of benzene, we must multiply the volume with the density.
Density = 0.879 g/cm3 or 879 kg/m3
Mass of benzene = Volume x Density
Mass of benzene = 5.087 x 879 = 4,471.5 kg
<em>ANSWER: Mass of benzene = 4,471.5 kg</em>
False....................................
Because There are frictional energy losses causing a slight downslope instead of a
<span>flat constant in the total energy</span>
I am not suer but i thx it is...
No they are falling the same distance and the weight doesn't matter. Neither does the mass and matter. It just depends on the height in which they are falling at the same amount of time.
Hoped I helped!
