Hydroelectric, which is usually generating electricity through use of a dam.
Solar, energy from the Sun.
Biomass, organic material formed from plant matter.
He has no acceleration because his velocity remains constant
In a solid the atoms are tightly packed together meaning that they vibrate in place slowly. In a liquid the energy gets faster and they have enough space between each other where they can move past one another. And in a gas the particles are moving very fast and they are spread out even further than a liquid.
Answer:
1) is equal to, 2) is equal to, connected and moving along the same track.
Explanation:
1) The speed of the small engine car <em>is equal to</em> the speed of the massive cargo car.
2) The magnitude of the acceleration of the small engine car <em>is equal to</em> the magnitude of the acceleration of massive cargo car because they are <em>connected and moving along the same track</em>.
