The figure shows two identical metal bars are different temperatures. What is the
Gala2k [10]

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:-

\alpha =\dfrac{\Delta l}{\Delta t\times l}

By putting the values we will get the answer.

\alpha=\dfrac{0.0001}{70\times 1}= 1.4\times 10^{-5}

Therefore the coefficient of thermal expansion of the metal will be 1.4 x 10⁻⁵ °c.

To know more about the coefficient of thermal expansion follow

The sum of three consecutive even integers is 36. let x represent the least consecutive integer. i really need help ;-; 1.) what
Sliva [168]
Anytime you have text problem you need to write equation just read text bit by bit and write equation as you are reading text!

It starts with "the sum" which means we are using + to sum some numbers.
Next is "three". which means we are summing some 3 numbers.
Next is" consecutive even integers" for that you need to know if 4 is one number than next consecutive even number is 6 or 4+2.
And all is equal to 36.
which means we write:
x + (x+2) + (x+4) = 36  where x is least of those numbers.

3x + 6 = 36
3x = 30
x = 10.

Least consecutive even integer in this task is 10.
