The mass of an object does not depend on its shape - it stays the same. Give an example that would prove this to be true.

Need in all of themmm only answer if you know plsssss

The speed of sound in ice, water, and steam is shown. what best explains the speed of sound in different states of matter? sound travels fastest in ice because energy is easier to transfer when the molecules are close together. sound travels slowest in steam because the sound has to move around the gas molecules that are far apart. sound travels fastest in ice because the temperature of solids is always greater, so the heat transfers the sound energy. sound travels slowest in steam because the pressure is so great the sound cannot travel though the steam particles.

Mechanical energy is when the amount of kinetic and potential energies added together remains the same. conserved created lost
