A. The scientist used books to look up the answers to her questions about African wild dogs and their interactions.

B. The scientist traveled to Africa and used her sense of sight and her sense of hearing to observe the wild dogs interacting in their natural habitat.

C. The scientist traveled to Africa and used an app on her mobile phone to measure the volume of the noises the wild dogs made while interacting.

second mirror gathers light from a faraway object and reflects it to another mirror. - a.

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

the list might look something like this:

-- baby human

-- piccolo

-- flute

-- 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.

the minimum amperage that the current in this wire would have to have so that its weight is completely supported by the magnetic force due to earth's field, assuming that no other forces except gravity act on it

  distance on the y-axis and time on the x-axis.

explanation:

the instantaneous velocity = change in position/time taken

the slope of the graph should give instantaneous velocity.

  slope of a graph = change in value of y -axis / change in values of x -axis

  comparing both the equations

    change in value of y -axis = change in position

  change in values of x -axis = time taken

so position values should be on the y axis and time values should be on the x axis.

distance on the y-axis and time on the x-axis.
