Aperson began running due east and covered 15 km in 2.0 hr. what is the average velocity of the person? show all your work!

Pl asaaap ! match the term to the correct description. a type of wave that transfers energy where the particles in the medium move perpendicular to the direction in which the energy is traveling. a type of wave that transfers energy where the particles in the medium move parallel to the direction in which the energy is traveling. movement that is back and forth, like an equal sign = a type of wave that transfers energy where the particles in the medium move in a circle motion while the energy travels left or right. movement that is like a t transfers energy from one location to another 1. wave 2. parallel movement 3. perpendicular movement 4. transverse wave 5. longitudinal wave 6. surface wave

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

Ryan is examining the energy of the particles in a bar of gold. what is ryan most likely studying?
