... So in 0.3 s, the chip releases 100 W × 0.3 s ∼ 30 J ∼ 3 · 108 erg which gets converted into the thermal energy of the air in the casing: (3k∆T /2) × nair V , where nair ∼ 3 × 1019 cm−3 (a number worth remembering). Solve for ∆T ∼ 15 K which feels about right (it’s hot in there!), and is certainly r ...

Note: Students should be supported in developing simple observation protocols to collect, analyze and report on the findings. ...

Continuous Spectrum—Kirchoff`s First Law
... Visual binaries, which can be seen in the telescope as two separate stars, are especially useful to astronomers. Over time, we can watch the two stars orbit around each other. We can measure the size of the orbit, and can calculate its actual size (in A.U.) if we know the distance of the binary. We ...
