12: They have more moons because they are bigger. They have a greater gravity field so they pull more on other objects. Gravity is like a blanket held taunt. If you put a big bowling ball in the center and place an orange on the outside the orange is going to want to go to the center, where the bowling ball is. Now if you add angular momentum to the equation you get gravity. Of course it isn't that simple but its the jist of it. Therefore, since Saturn and Jupiter have a higher gravitational pull on other celestial objects they pull on more matter around them, like asteroids and such. These asteroids clump together and form their planets.
Answer:
Kp of the reaction is 0.0215
Explanation:
Step 1: Data given
Partial pressure at the equilibrium of N2 = 0.22 atm
Partial pressure at the equilibrium of O2 = 0.19 atm
Partial pressure at the equilibrium of NO = 0.030 atm
Temperature = 2200 °C
Step 2: The balanced equation
N2(g) + O2(g) ⇌ 2NO(g)
Step 3: Calculate Kp
Kp = (pNO)² /(pO2)*(pN2)
Kp = (0.030)²/(0.19*0.22)
Kp = 0.0215
Kp of the reaction is 0.0215
Answer:
By using the techniques of archeology.
Explanation:
Students recover an individual's remains from a surface grave by using the techniques of archeology field to scrape away the layers of soil from that remains in a way that the remains can't be damaged. If they find the remains within 10 centimeters of digging, they can dig down further in order to dig out all the remains safely. The instruments of archeology field are used because they are light and can be used to dig out fossils of ancient organisms.
Answer:
kilograms of sulfur will be emitted from coal plants in two weeks
Explanation:
Power produced by power plants in the United States :P
P=![2.6\times 10^{11} Watts](https://tex.z-dn.net/?f=2.6%5Ctimes%2010%5E%7B11%7D%20Watts%20)
1 Joule = Watts × Seconds
Watts = Joule/Second
P=![2.6\times 10^{11} J/s](https://tex.z-dn.net/?f=2.6%5Ctimes%2010%5E%7B11%7D%20J%2Fs)
This means that
Joules of enrgy is produced in one second.
So, energy produced in 2 week:
1 week = 7 days
1 day = 24 hours
1 hour = 3600 seconds
2 week = 2 × 7 × 24 × 3600 s=1,209,600 s
Energy produced in 1,209,600 s: E
![E=2.6\times 10^{11} J/s\times 1,209,600 s](https://tex.z-dn.net/?f=E%3D2.6%5Ctimes%2010%5E%7B11%7D%20J%2Fs%5Ctimes%201%2C209%2C600%20s)
Coal has an energy content =![2.4\times 10^7 J/Kg](https://tex.z-dn.net/?f=2.4%5Ctimes%2010%5E7%20J%2FKg)
Mass of coal used while producing E amount of energy: m
![m\times 2.4\times 10^7 J/Kg=E](https://tex.z-dn.net/?f=m%5Ctimes%202.4%5Ctimes%2010%5E7%20J%2FKg%3DE)
![m=\frac{E}{2.4\times 10^7 J/Kg}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7BE%7D%7B2.4%5Ctimes%2010%5E7%20J%2FKg%7D)
![m=\frac{2.6\times 10^{11} J/s\times 1,209,600 s}{2.4\times 10^7 J/Kg}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B2.6%5Ctimes%2010%5E%7B11%7D%20J%2Fs%5Ctimes%201%2C209%2C600%20s%7D%7B2.4%5Ctimes%2010%5E7%20J%2FKg%7D)
![m = 1.3104\times 10^{10} kg](https://tex.z-dn.net/?f=m%20%3D%201.3104%5Ctimes%2010%5E%7B10%7D%20kg)
Percentage of sulfur in coal = 4% by mass
Mass of sulfur produced from
in 2 weeks:
![\frac{4}{100}\times 1.3104\times 10^{10} kg=5.2416\times 10^8 kg](https://tex.z-dn.net/?f=%5Cfrac%7B4%7D%7B100%7D%5Ctimes%201.3104%5Ctimes%2010%5E%7B10%7D%20kg%3D5.2416%5Ctimes%2010%5E8%20kg)
Your answer should be "D."
Early computers were like "walkie-talkies."
They were used by the government to exchange all sorts of data during the Cold War.
I hope this helps! :)
