The pattern is: if you multiply the first two numbers in each set you will get the last number in that set
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.

Scientific notation is the way that scientists easily handle very large numbers or very small numbers. For example, instead of writing 0.0000000056, we write 5.6 x 10-9.
So, if we are dealing with 965000000000000, then the answer would be:
9.65 x 10^14
Answer:
C
Step-by-step explanation:
(c + 1)(c+1) = c² + c + c + 1 = c² + 2c + 1
