On the other hand, E-beam sterilization can be harmful to products containing batteries or electronic components. It can also degrade rubber and polypropylene, but these materials now come in grades that are E-beam compatible, Wilson notes.
A trajectory is the path of an object through space, or the path of life that a person chooses. The prefix tra- is short for trans-, which means across (think transport and transit) and the ject comes from jacere, which means throw and is also the root of the word jet.
Velocity is the rate at which an object changes its position. It is a vector quantity. The direction of velocity is the direction in which the object is moving. The absolute value or the magnitude of velocity is speed. Velocity can also be defined as the displacement of an object in a specified direction.If the object returns to its starting point then its velocity is zero.he direction of velocity is the direction in which the object is moving. The absolute value or the magnitude of velocity is speed. Velocity can also be defined as the displacement of an object in a specified direction.
