It is desired to make a 20 Ω coil of wire, which has a zero thermal coefficient of resistance. To do this, a carbon resitor fo resistane R1 is placed in series with an iron resistor of resistance R2 the proportions of iron and carbon are so chosen that R1+R2=20Ω for all temperatures near 20∘C. How long are R1 and R2? αcarbon =− 0.5 × 10^−3.∘ C−1 , α iron = 5×10^−3.∘C(−1)

In a double slit experiment, the distance between the slits is 5.0 mm and the slits are 1.0m from the screen. Two interference patterns can be seen on the screen one due to light with wavelength 480nm, and the other due to light with wavelength 600nm. What is the separation on the screen between the third order bright fringes of the two interference patterns?
