Consider the image above and select the answer that best represents the skiers energy.
Masteriza [31]

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.

Why aren't all atoms radioactive?
egoroff_w [7]

Explanation:

Some atoms are unstable. They have too much energy or the wrong mix of particles in the nucleus. So to make themselves more stable, they breakdown (or decay) and get rid of some matter and/or some energy. This is called radioactive decay and isotopes of atoms that do this are called radioisotopes.

The process is spontaneous and random. You can't do anything to speed it up or slow it down and you can't predict when it will happen. The only reason we can do any calculations on radioisotopes is because there are huge numbers of atoms in most samples so we can use statistics to accurately predict what's most likely to happen.
