Potential Energy Equation (GPE = mgh)
Kinetic Energy Equation (KE = 1/2 mv2)
1) An object has a mass of 25 kg and is sitting on the top shelf at a store that is 10 m high; find
the object's gravitational potential energy

10

Explanation:

weight=25x9.2=230

25x9.2x10=2300

2300/230=10

B: KE = 1/2mv squared

Explanation:I did the assignment on edge.

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.
