Listed following are several fictitious stars with their luminosities given in terms of the sun's luminosity (lsun) and their distances from earth given in light-years (ly).
rank the stars based on how bright each would appear in the sky as seen from earth, from brightest to dimmest. if two (or more) stars have the same brightness in the sky, write the stars one below the other.
compare the result with the ranking of luminosity from largest to smallest.
a) enzo: 200 lsun , 20 ly
b) ferdinand: 400 lsun , 20 ly
c) nismo: 100 lsun , 8 ly
d) lotus: 400 lsun , 40 ly
e) shelby: 100 lsun , 10 ly

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.
