A piano has 12 notes on it. The notes (keys) are from A - G. Each note can be a flat or a sharp. Each note will either be higher or lower in pitch than the one being played. If you played Middle C on the piano and then played the next key on the right (which would be a D if going one full step up) it would be slightly higher in pitch.
a quarter note is the same on every instrument. In 4/4 time it is one beat.
no
No, not every note is sharpened, or raised a half step. It's just that note. For example, in a measure, if the note A is sharpened, every A in that measure will be sharpened unless naturalized.
They are the same as the piano or if you need it higher every note for the piano make it the next note up( G=A A=B B=C# etc.)
It is because C and D are two half steps apart. Flats make a note one half step lower and sharps make a note one half step higher, so that C# and Db are the same. This is the same for every instrument.
An enharmonic note is a note that has two names but have the same fingering
I believe that this question does not need the "accurate" answer because not every single Muslim is the same. Please note that if there are bad muslims; in everytime and in everywhere and in every religion, there are bad and good people.

The same note name, yes. They could possibly be different pitches.
a note that has the same pitch but a different letter name
counterpoint
