An ethernet cable is 4.15 m long. the cable has a mass of 0.210 kg. a transverse pulse is produced by plucking one end of the taut cable. the pulse makes four trips down and back along the cable in 0.765 s. what is the tension in the cable?

95.3 N

Explanation:

The tension in the cable is found by the equation:

Where is the mass density, and is velocity.

First we find mass density:

--> is mass: and is length of the cable: , so:

And the velocity:

the time is and in that time the pulse went down and back along the cable 4 times, if one time down and back is:

2*4.15m=8.3m,

four times this path is:

4*8.3m=33.2m

thus, the velocity is:

And with this data we can now calculate the tension:

The tension is 95.3N

gravititional force is a force that is acting around you, it is non-contactable and it is a force that pulls you to the core of the earth.

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.
