The coefficient of thermal expansion of the metal will be 1.4 x 10⁻⁵ °c.
<h3>What is thermal expansion?</h3>
Every material has its property of contraction or expansion by the change of temperature. The expansion and contraction of any material are indicated by a coefficient this coefficient is called the coefficient of thermal expansion.
Here we have the following data:-
l₁= 1.000 m
l₂ = 1.001 m
Δ = 70° C
The formula for calculating the coefficient of linear expansion will be:-
By putting the values we will get the answer.
Therefore the coefficient of thermal expansion of the metal will be 1.4 x 10⁻⁵ °c.

Answer:
7.72% decrease
Step-by-step explanation:
Okay so all you do for this one is add the two angles already inside the triangle, (so 69+66 which equals 135) then subtract 135 from 180, which equals 45.
So x would be 45 degrees
I'm not sure what the question is.
Given:
Flash drive capacity 1,000 megabytes
Initial content before transfer of files 36.5 megabytes
After 125 seconds, there were 549 megabytes on the drive.
549 - 36.5 = 512.5 megabytes is the weight of the transferred files.
512.50 megabytes / 125 seconds = 4.1 megabytes per second
The rate of transfer is 4.10 megabytes per second.
1000 - 549 = 451 megabytes free space.
451 megabytes / 4.1 megabytes per second = 110 seconds
It would take an additional 110 seconds to completely fill up the flash drive.
