The cheetah can maintain its maximum speed for only 7.5 s. what is the minimum distance the gazelle must be ahead of the cheetah to have a chance of escape? (after 7.5 s the speed of cheetah is less than that of the gazelle.) answer in units of m.

Basically the cheetah is running 31.5km/h faster than the gazelle. So to determone how long it will take to cover 9mm at that speed, you have to a lot of work. If you skip all of that work, the answer is 1.60m seconds

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.

im srry but ur wrong the answer is d a smooth rock, some red dirt, and an empty bird's nest.
