?0 = 4?*10-7 Tm/A (the T is Tesla, m is meters, A is amps) Astudent on some distant planet plotted 1/T^2 vs I for a bar magnetsuspended inside a Helmholtz coil like in exp. 6.1. They got aslope of 15 LaTeX: frac{1}{Acdot s^{2:}}1 A ? s 2. The radius ofHelmholtz coil is 7.6 cm. The number of turns is 141. What is thevalue of the C constant on this planet? Give the answer in LaTeX:frac{1}{Tcdot s^2}1 T ? s 2 rounded to one decimalplace.

[01] The lowest natural temperature ever directly recorded atground level on Earth is ?128.6 °F, at the Soviet Vostok Station inAntarctica on 21 July 1983. Calculate v_rms of a N2 moleculeat that temperature. [02] On the other hand, the highest air temperature recorded onEarth is 134.1 °F, 10 July 1913 at Furnace Creek Ranch, in DeathValley in the United States. Calculate v_rms of a N2 moleculeat that temperature. [03] Also find out the ratio of the two RMSspeed.
