Asolid disk of mass m and radius r is moving with a constant angular velocity of w when an external torque begins to slow the disk down. it goes through exactly x revolutions before coming to a stop. a. derive an expression for the net torque applied to the disk. express your answer in terms of the givern variables and fundamental universal constants b. if the force causing the torque had been applied at a ½ the distance, by what factor would the total revolutions completed before stopping change?

b would be the answer

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.

higher potential

explanation:

because it is in a high speed so it must move into a of high potential
