for small changes in temperature, the formula for the expansion of a metal rod under a change in temperature is: g-l=al(t-t), wh
ere g is the length of the object at temperature t, and l is the length at temperature t, and a is a constant which depends on the type of metal. a rod is 135 cm long at 115 degrees f and made of a metal with a=10^-3. write an equation giving the length of this rod at temperature t(because a=10^-3 is very small, give an exact answer: do not round expand multiplied numerical products to get rounded decimals).
Equation giving the length of this rod at temperature is g = 0.000085t + 84.991075 cm.
What is temperature ?
A temperature is a unit used to represent voguishness or coolness on any of a number of scales, including Fahrenheit and Celsius.
According to temperature, heat energy will naturally move from a hotter( body with an advanced temperature) to a colder( body with a lower temperature)( one at a lower temperature).
