a mechanical wave is a wave that is an oscillation of matter, and therefore transfers energy through a medium. while waves can move over long distances, the movement of medium transmission-the material- is limited. again, the oscillating material does not move far away from its initial equilibrium position ;)
Answer:
When the spring in the ballistic pendulum is compressed, <em>energy is stored up in the spring as potential energy. </em>When the steel ball is launched by the spring, <em>the stored up potential energy of the compressed spring is transformed and transferred into the kinetic energy of the steel ball as it flies off to hit its target. </em>On hitting the soft target, <em>some of the kinetic energy of the steel ball is transferred to the soft target (since they stick together), and they both start to swing together</em>. During the process of swinging, the system's energy is transformed between kinetic and potential energy. <em>At the maximum displacement of the ball from its point of rest, all the energy is converted to potential energy of the system</em>. <em>At the lowest point of travel (at the rest point), all the energy of the system is transformed into kinetic energy. </em>In between these two points, <em>energy the energy of the system is a combination of both kinetic and potential energy.</em>
In the end, all the energy will be transformed and lost as heat to the surrounding; due to the air resistance around; bringing the system to a halt.
A boiling pot of water (the water travels in a current throughout the pot), a hot air balloon (hot air rises, making the balloon rise) , and cup of a steaming, hot liquid (hot air rises, creating steam) are all situations where convection occurs.

Answer:
B.Ionizing radiation is the correct answer.
Explanation:
Ionizing radiation has sufficient energy that it can convert atoms and molecules into ions.
It has a sufficient amount of energy that it can separate tightly confined electrons from the orbit of an atom and causing that atom to become ionized.
