Answer:
b) Endothermic Chemical Reactions in a solid
Explanation:
Endothermic reactions consume energy, which will result in a cooler solid when the reaction finishes.

Answer:
The average velocity is 0.203 m/s
Explanation:
Given;
initial displacement, x₁ = 20 yards = 18.288 m
final displacement, x₂ = ¹/₃ x 18.288 = 6.096 m
change in time between 5:02 PM and 5:03 PM, Δt = 3 mins - 2 mins = 1 min = 60 s
The average velocity is given by;
V = change in displacement / change in time
V = (x₂ - x₁) / Δt
V = (18.288 - 6.096) / 60
V = 0.203 m/s
Therefore, the average velocity is 0.203 m/s
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

Radio waves are radiated by charged particles when they are accelerated. They are produced artificially by time-varying electric currents, consisting of electrons flowing back and forth in a specially-shaped metal conductor called an antenna. ... Radio waves are received by another antenna attached to a radio receiver.
