Answer:
I need an image, but if you're talking about Potential and Kinetic energy, I will determine for you:
Explanation:
Potential Energy: stored energy that depends upon the relative position of various parts of a system.
Kinetic Energy: the form of energy that an object or a particle has by reason of its motion.
Therefore, if the skier is on top of the mountain, they would have potential energy since their energy from the ground to the top of the surface is stored. But, if the skier is in motion/mid-air from the top of a mountain, their energy is kinetic (in motion) because their stored energy (potential) is released as they step off of the surface.
If you, for example, poured it onto a wide cup with a volume equal to the total volume of the sand particles, the sand would not spread out to fill the container but would bunch up together in the middle.
That is true.
In the solid state the molecules of water have the lowest energy content.
To pass from solid state to liquid stated water needs to gain some energy to increase vibration and motion of the molecules and reach a higher energy states.
To pass from liquid state to vapor (gaseous state) the molecules of water have to gain more energy to increase more the motion of the molecules and reach a more energetic stated.
Then you can think that when the water vapor becomes liquid (droplets) it needs to release some energy.
The droplets formed on a glass of ice water is an example of water condensation, one of the processes of the water cycle.
The droplets on the external surface of a cold glass are the result of condensation of water.
Condensation is the pass from vapor state to liquid state. As whe have stated, when water passes from vapor state to liquid state it has to release energy because liquid state is lower in energy than vapor (the molecules in water experiment slower motion than molecules of vapor).
The sun is the original source of solar energy, hydroelectric energy, food energy, coal energy, oil energy, and wind energy.
The sun is NOT the original source of <em>nuclear energy. (b)</em>
The net force on the box parallel to the plane is
∑ F[para] = mg sin(24°) = ma
where mg is the weight of the box, so mg sin(24°) is the magnitude of the component of its weight acting parallel to the surface, and a is the box's acceleration.
Solve for a :
g sin(24°) = a ≈ 3.99 m/s²
The box starts at rest, so after 7.0 s it attains a speed of
(3.99 m/s²) (7.0 s) ≈ 28 m/s
