You are installing a new spark plug in your car, and the manual specifies that it be tightened to a torque that has a magnitude of 46 n · m. using the data in the drawing, determine the magnitude f of the force that you must exert on the wrench.

If the force is perpendicular to the wrench, and If we use a wrench that is 0.2m long, then

Explanation:

As there is no draw in the question, we can imagine the spark plug being in a point were the wrench starts, and the force being exerted where the wrench ends. As the torque is a vectorial quantity, we imagine the force being exerted in a direction perpendicular to the wrench, and the wrench with a longitude l. The definition of torque is

and as we exerted the force perpendicular to the wrench, θ is 90°, so sen(90°) is equal to 1. Then

Now, if the wrench is 0.2 m long, then

is the magnitude F of the force exerted to get 46 Nm of torque.

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.

pretty sure it's false
