In which art genre did we first see characters such as superman, batman, and spiderman?

It’s comics. The movies/shows came after.

(Hope this helps!)

answer; 10 foot-candles

c, d, e, f, g, a, b, and c.

sometimes western music will also use solfege. the names of these are do ra me fa sol la si (or ti) and do.

to indicate a note a half step higher or lower then the original note, you would say c # (for a half a step above c) or bb (for half a step below b)
