The three previous manufacturing revolutions that Mr. Scalabre mentioned and their year of occurrence are:
- The steam engine in the mid-19th Century
- The mass-production model in the early 20th Century
- The first automation wave in the 1970s
<h3>What is a Manufacturing Revolution?</h3>
This refers to the process of change from a handicraft economy to industry production-based production.
Hence, we can see that Mr. Scalabre believes we are not growing in productivity because there has not been enough automation to perform the tasks needed.
The effect of robotics is making an impact on productivity because a lot of complex, difficult tasks are done by machines.
3D printing has made an impact on productivity because there is a reduction in the pressing cycle and errors due to negligence are reduced.
The role the engineers have to play in the next revolution is that they would have to produce mathematical model that can be used to produce better AIs

Answer:
1. 
2. 
Explanation:
1.
Given:
- height of the window pane,
- width of the window pane,
- thickness of the pane,
- thermal conductivity of the glass pane,
- temperature of the inner surface,
- temperature of the outer surface,
<u>According to the Fourier's law the rate of heat transfer is given as:</u>
here:
A = area through which the heat transfer occurs = 
dT = temperature difference across the thickness of the surface = 
dx = t = thickness normal to the surface = 
2.
- air spacing between two glass panes,
- area of each glass pane,
- thermal conductivity of air,
- temperature difference between the surfaces,
<u>Assuming layered transfer of heat through the air and the air between the glasses is always still:</u>
Ik i am thank you tho xoxo
Answer:
1.693242
Explanation:
The colors in the Light emitting diodes have been identified by wavelength which is measured in nano-meters. Wavelength is a function of LED chip material. The LED diode which has a = 632 then A1 will be 1.63242, this is calculated by 1 / 632. Wavelength are important for human eye sensitivity. The colors emitted from the LED will depend on the semiconductor material.
