<h2>The increase in length = 1.87 x 10⁻²</h2>
Explanation:
When copper rod is heated , its length increases
The increase in length can be found by the relation
L = L₀ ( 1 + α ΔT )
here L is the increased length and L₀ is the original length
α is the coefficient of linear expansion and ΔT is the increase in temperature .
The increase in length = L - L₀ = L₀ x α ΔT
Substituting all these value
Increase in length = 27.5 x 1.7 x 10⁻⁵ x 35.9
= 1.87 x 10⁻² m
The branch of physics that deals with the study of force energy and motion is classic mechanics
Sherry who says one factor is the length of the path of sunlight is correct.
<h3>
Factors affecting light scattering</h3>
There are two main factors which affects light scattering, and they include the following;
- the size of the particles
- wavelength of the light
length of the path of sunlight is equivalent to wavelength of the light.
Thus, we can conclude that Sherry who says one factor is the length of the path of sunlight is correct.
