Answer:
An element is a pure substance and is made of only one type of atom; it cannot be broken down into a simpler substance.
Mr. Roentgen's x-rays allowed scientists to measure the size of the atom. The x-rays were small enough to discern the atomic clouds. This was done by scattering x-rays from atoms and measuring their size just as Rutherford had done earlier by hitting atoms with other nuclei starting with alpha particles.
Explanation:
Displacement=Velocity×time
=24.7×16.00
=395.2m
Therefore the displacement within the time interval is 395.2m
