The answer is : Evaporation
Examples of Newton's 2nd Law If you use the same force to push a truck and push a car, the car will have more acceleration than the truck, because the car has less mass. It is easier to push an empty shopping cart than a full one, because the full shopping cart has more mass than the empty one.
This is a question about converting energy from one form to another.
<span>While it is sitting on the ledge, it isn't moving, so at that point it doesn't have any kinetic energy. What it has is gravitational potential energy due to its height above the ground. </span>
<span>Just as it lands, it's at ground level, so it doesn't have any gravitational potential energy anymore. </span>
<span>The reason is that on the way down, it sped up, so all its original gravitational potential energy was turned into kinetic energy. </span>
<span>So if you can work out how much potential energy it had to start with, you will know that that is how much kinetic energy it ended up with just before it landed. </span>
<span>potential energy = m * g * h </span>
<span>where m is the mass, g is the acceleration due to gravity and h is the height </span>
potential energy = 4.45 * 9.81 * 0.800 = 35.3 J
Hope that helps. Please give me Brainlyest answer. :]
Alpha Centauri is 4.4 lightyears away. Traveling at 1/10 speed of light it would take you 44 years.
