Calculate the kinetic energy of a hollow sphere having a mass of 1500 gm with a diameter of 3 m, and moving around its own axis with an angular velocity of 66 degrees/sec.

answer: b.

explanation:

i don't understand is there any other way you can rephrase it plz let me know in the comments and i will do it.

explanation:

i am pretty sure it is c because when people are closer together, they cannot move as freely. picture being in a mostly full elevator, for instance. the people are right next to you, and you can barely move.

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.
