Homework Statement
In a certain experiment, the power (P) radiated by a light bulb filament was measured as a function of the filament's absolute temperature (T).
Data:
P(W)
0.45
0.95
1.8
3.5
5.6
T(K)
1000
1200
1500
1800
2000
(a) Plot the data (Done)
(b) Assume a power function and re-plot the data.
Homework Equations
Unsure.
The Attempt at a Solution
I plotted the data and it looks like a natural logarithm. I'm not sure what to do next. Raising each T value to the power of 2 straightens out the curve a bit but not completely. Is that what it means to assume a power function? If a power function is y=kx^a, how do I know which exact a to take and where do I get k from? Thanks.
