Answer:
Define the Problem
Background Research
Write a Hypothesis
Carry Out the Experiment
Analyze Data
Draw a Conclusion
Explanation:
First of all, identify the first and last steps before figuring out the middle.
In order, the first and last steps should be
Define the Problem
...
Draw a Conclusion.
Next, you can add your answers in the middle, from beginning to end. That would be,
Define the Problem
Background Research
Write a Hypothesis
Carry Out the Experiment
Analyze Data
Draw a Conclusion
Let me know if this is inaccurate as I am learning everyday. Hope this helped!
We have to know how urbanization causes pollution.
The reason is: People in urban areas consume more energy, food, and water.
Urbanisation is one of the major problem towards pollution. The smoke from automobiles, factories and power generators make air unhealthy. Also chemical spills and other toxic gases contaminate in air.
The mixing of toxins in the soil is polluting soil which disturbs eco-system.
The high density population in urban area consume more energy , food and water which causes pollution.
Answer:
B.) 1.3 atm
Explanation:
To find the new pressure, you need to use Gay-Lussac's Law:
P₁ / T₁ = P₂ / T₂
In this equation, "P₁" and "T₁" represent the initial pressure and temperature. "P₂" and "T₂" represent the final pressure and temperature. After converting the temperatures from Celsius to Kelvin, you can plug the given values into the equation and simplify to find P₂.
P₁ = 1.2 atm P₂ = ? atm
T₁ = 20 °C + 273 = 293 K T₂ = 35 °C + 273 = 308 K
P₁ / T₁ = P₂ / T₂ <----- Gay-Lussac's Law
(1.2 atm) / (293 K) = P₂ / (308 K) <----- Insert values
0.0041 = P₂ / (308 K) <----- Simplify left side
1.3 = P₂ <----- Multiply both sides by 308
Answer:
The equation for the Kinetic Energy, 
, of the photo-emitted electrons is given as follows;
Please find attached the required plot of the kinetic energy versus the frequency
Explanation:
The equation for the Kinetic Energy, , of the photo-emitted electrons is given as follows;
Where:
h = Planck's constant = 6.63×10⁻³⁴ J·s
f = Frequency
BE = Binding Energy = 2.71 eV for Calcium metal
f₀ = Threshold frequency for the material
The ionization energy is the energy required to free an electron from an isolated atom
