I am absolutely sure that if something is hot, it contain thermal energy only because <span>if a given body is heated its electrons start to move very fast which means that thermal energy is being produced. Hope everything is clear! Regards!</span>
Mechanical weathering is actually breaking down of rocks into smaller pieces by natural forces. Any weathering processes that can cause the physical breakdown of rocks without any type of change in the chemical composition of rocks, called mechanical weathering.
So, looking at each of the definitions in the options, we can easily choose:
1. Hydration : It's a process of absorbing water by substance.
2. Carbonation: It's a process of Carbon Dioxide dissolving in liquid (mostly water).
3. Oxidation : It's a process of oxygen reacting with some element.
4. <span>Exfoliation: It's a process where the rocks erodes by peeling off in sheets or layer by layer rather than grain by grain.
As you can see the last one </span><span>Exfoliation matches with the definition of mechanical weathering. It's one of its types.</span>
Answer:
I don't think the information is complete
The movie Star Wars<span> is a space
opera interstellar epic which uses science and technology in its settings and storylines, although its main
focus is not necessarily on science.</span>
Many
elements in the films appear to defy simple laws of physics.<span>
One of which is the falling of spaceships when they are hit by a laser beam.
Experts said, this is one good example because without gravity in space, ships
should travel in the direction of the impact instead of dropping like a stone.</span>

The kinetic energy of an object is given by:
where m is the mass of the object and v its velocity.
The car in this problem has a mass of m=600 kg and a velocity of v=10 m/s, therefore if we put these numbers into the equation, we find the kinetic energy of the car:
