Can someone please help me and write the answers? i need this and it’s really important!!

-- Kinetic energy is the energy of mass in motion.  The amount is determined by the mass of whatever is moving, and its speed.

-- Potential energy is the energy that's stored up in some form, not being used yet but ready to be used when you want it.

For example, one form of it is chemical potential energy, like in a battery, or a match.  You get the energy out of a battery when you connect it to a motor or a light.  You get the energy out of as match when you make the tip hot and it flares up.

This question is asking about gravitational potential energy.  An object has stored energy just by being up high, like a bowling ball on a shelf.  You get the energy out of it just by dropping it ... possibly enough to crack the floor !

The amount of this kind of potential energy is determined by the mass of the object, and how high up it is.

-- Getting the answers from other people doesn't help you a bit, until you understand them and can answer the question on your own.

v 154.9= 0.9 length length s little over 154.9cm

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.
