Final answer:
The transformation that is a dilation is option 4) Dilation, which changes the size of a figure without altering its shape.Regarding the rest of the information provided, it seems to be related to physics, specifically rotational dynamics and kinematics.
Step-by-step explanation:
The transformation that is a dilation among the given options is 4) Dilation.
A dilation is a transformation that changes the size of a figure but not its shape.
The other transformations mentioned, such as translation, rotation, and reflection, alter the position or orientation of a figure but do not change its size.
Regarding the rest of the information provided, it seems to be related to physics, specifically rotational dynamics and kinematics, which is not directly related to answering the question about dilation in a mathematics context.
