<span>CD stands for Compact Disk and ROM stands for Read Only Memory. CD-ROMS were designed to store information that the computers can read and you cannot overwirte on it. S,o the answer is the option C.: A CD-ROM is a compact disk that contains stored information that can be read on a computer.</span>
In order to calculate the unknown reaction force, we need to know that the sum of forces pointing down is equal the sum of the forces pointing up, so all forces will be in equilibrium.
So we have:
A: Some physical properties change, but the substance keeps its identity.
Density = (mass) / (volume)
Density = (35.7 g) / (17 cm³)
Density = 2.1 g/cm³
Answer:
Energy implies as the object’s capability to perform work. It is something that cannot be created or destroyed but can only be transformed. An object loses its energy, when it performs work, whereas it gains energy when the work is performed on it. Energy is broadly classified as kinetic energy and potential energy. While kinetic energy is the energy which an object contains because of a particular motion.
On the other hand, potential energy is the stored energy, because of its state of rest. As both the two forms of energy are measured in joules, people get easily confused between these two. So, take a read of the article which will help you to understand the differences between kinetic and potential energy.
