Farah claps his hands 600 times in 60 seond whats is the frequency and period

c)as speed changes, wavelength and frequency change.

everything changes!

there is no correct list among the choices you've provided.

the list might look something like this:

-- baby human

-- piccolo

-- flute

-- soprano singer

-- trumpet

-- tenor singer

-- trombone

-- baritone singer

-- baritone horn

-- bass singer

-- tuba

since i had to make up the list myself, i made it easy on myself, and i didn't try to shuffle the string instruments and woodwinds into it too.

i think the answer is tomato juice? not entirely sure though
