Answer:
c. A Generator
Explanation:
The whole point of a generator is to produce electrical energy. The generator will use a mechanical motor usually running off of gas to produce electricity.
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>
Electricity is the flow of electrical power or charge.
Answer:
In a third class lever, the effort is located between the load and the fulcrum. If the fulcrum is closer to the load, then less effort is needed to move the load. If the fulcrum is closer to the effort, then the load will move a greater distance. ... These levers are useful for making precise movements.
Answer:
A possible answer would be that chemical properties depend on phisical properties if and if only the phisical properties depend on the chemical ones ( see the laws of thermodinamics)
