An astronaut is taking a space walk near the shuttle when her safety tether breaks. what should the astronaut do to get back to the shuttle? view available hint(s) an astronaut is taking a space walk near the shuttle when her safety tether breaks. what should the astronaut do to get back to the shuttle? attempt to "swim" toward the shuttle. take slow steps toward the shuttle. take a tool from her tool belt and throw it away from the shuttle. take the portion of the safety tether still attached to her belt and throw it toward the shuttle.

Take a tool from her tool belt and throw it away from the shuttle.

Explanation:

According to Newton's third law of motion, when two bodies interact between them, appear equal forces and opposite senses in each of them.  

To understand it better:  

Each time a body or object exerts a force on a second body or object, it (the second body) will exert a force of equal magnitude and direction but in the opposite direction on the first.

So, if the astronaut throws one of her tools away from the shuttle (in the opposite direction of the shuttle), according to  Newton's third law, she will be automatically moving towards the shuttle and be safe.

where is the circuit diagram ?

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

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.
