The linear expansion of a solid is described by ℓ = ℓo ( 1 + a.Δt ) where ℓ and Δt are measured
variables, ℓo is constant but unknown. Determine a .

This has to be done by putting the above question in the form y=mx+b and "a" will be determined by either the slop or intercept

anonymous · Answer

a is also a constant|dw:1380999825182:dw| the intercept is zero the gradient is the product of the initial length and linear expansion
