A soccer player kicks a 0.5 kg ball and accelerates it at 50 m/s2. What force does the player apply to the ball?

What is the conversion factor between kg/m^3 and g/m^3. express your experimental values for the densities in kg/m^3.

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.

The movement of electrons between atoms is called an
