Electronics and inhabitants of the International Space Station generate a significant amount of thermal energy that the station must get rid of. The only way that the station can exhaust thermal energy is by radiation, which it does using thin, 1.6 mm -by-3.8 mm panels that have a working temperature of about 6°C. How much power is radiated from each panel? Assume that the panel are in the shade so that the absorbed radiation will be negligible. Assume that the emissivity of the panels is 1.0. Hint: Don't forget that the panels have two sides!

Suppose a diode consists of a cylindrical cathode with a radius of 6.200×10^−2 cm , mounted coaxially within a cylindrical anode with a radius of 0.5580 cm . the potential difference between the anode and cathode is 260 v . an electron leaves the surface of the cathode with zero initial speed (v initial=0). find its speed vfinal when it strikes the anode.
