Answer:
The initial temperature will be "385.1°K" as well as final will be "128.3°K".
Explanation:
The given values are:
Helium's initial volume, v₁ = 6 m³
Mass, m = 1.5 kg
Final volume, v₂ = 2 m³
Pressure, P = 200 kPa
As we know,
Work, 
On putting the estimated values, we get
⇒ 
⇒ 
⇒ 
Now,
Gas ideal equation will be:
⇒ 
On putting the values. we get
⇒ 
⇒ 
⇒ 
(Initial temperature of helium)
and,
⇒ 
On putting the values, we get
⇒ 
⇒ 
⇒ 
(Final temperature of helium)
Answer:
Use a story structure,
Explanation: Usually story engage the audience.
Answer:
The tool's trajectory in a CAM program refers to the places where the tool will be during the work. It is important to review it before generating the program for the following reasons
1. analyze the machining strategy and identify which one is better for each piece.
2.Avoid the collision of the tool holder with the work piece.
3.Avoid the shock of the tool with the piece.
4. Prevent the collision of the tool with elements that are not displayed on the CAM such as clamping flanges or screws.
Note, I answered from a general environmental perspective.
Answer:
<u>True</u>
Explanation:
It is quite true that because<em> people are becoming more aware of our environment,</em> environmental issues like global warming and climate change are now hotly debated topics among citizens.
Hence, it has created a need for scientists and engineers to help citizens and companies make valid decisions concerning products and practices that would reduce the effects of climate change.
For example, the following practices have been recommended:
- cutting of greenhouse gases emitted by cars and companies.
- shifting to eco-friendly building designs.
- reinventing the waste recycling processes.
