Answer: c. expansion coefficients.
Explanation: Bimetallic strips used as adjustable switches in electric appliances consist of metallic strips that must have different expansion coefficients.
I found the answer on Quizlet. :)
You didn't give us a photo of Figure 4-18, so we don't know anything about
the sports car. But here's how to answer the question on your own:
Acceleration = (change in speed) divided by (time for the change)
and
Change in speed = (end speed) minus (start speed)
So, the garbage truck's acceleration is ...
(100 km/hr - 0) / (10 sec)
= 10 km/hr per second .
Calculate the acceleration of the sports car the same way,
and then you can compare them.
The answer is d because you have to make sure that everything is right
