Answer:
The material cost for making one ton of the brass sample that I have is $8149.04.
Explanation:
Density of copper = 8.96 g/cm^3 = 8.96×10^-3 kg/cm^3
Price of copper = $6.13/kg
Price of copper per volume = 8.96×10^-3 kg/cm^3 × $6.13/kg = $0.0549/cm^3
Density of zinc = 7.14 g/cm^3 = 7.14×10^-3 kg/cm^3
Price of zinc = $1.8/kg
Price of zinc per volume = 7.14×10^-3 kg/cm^3 × $1.8/kg = $0.0129/cm^3
Price of brass per volume = 0.0549 + 0.0129 = $0.0678/cm^3
Density of brass I have is 8.32 g/cm^3 = 8.32 g/cm^3 × 1 kg/1000 g × 1 ton/1000 kg = 8.32×10^-6 ton/cm^3
Price = $0.0678/cm^3 ÷ 8.32×10^-6 ton/cm^3 = $8149.04/ton
Answer: No
Explanation:
The force F required is equal to the Force exerted in stretching the first material since conditions are the same
Answer:im so sorry i cant find anything either ask your teacher for some help is the best thing i can do
516.154 megawatts of heat are <em>exhausted</em> to the river that cools the plant.
By definition of energy efficiency, we derive an expression for the energy rate exhausted to the river (
), in megawatts:
(1)
Where:
- Efficiency.
- Electric power, in megawatts.
If we know that
and
, then the energy rate exhausted to the river is:
![Q_{out} = \left(\frac{1}{0.39}-1 \right)\cdot (330\,MW)](https://tex.z-dn.net/?f=Q_%7Bout%7D%20%3D%20%5Cleft%28%5Cfrac%7B1%7D%7B0.39%7D-1%20%5Cright%29%5Ccdot%20%28330%5C%2CMW%29)
![Q_{out} = 516.154\,MW](https://tex.z-dn.net/?f=Q_%7Bout%7D%20%3D%20516.154%5C%2CMW)
516.154 megawatts of heat are <em>exhausted</em> to the river that cools the plant.
