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:
Most of this water is locked up in ice, and another 20.9% is found in lakes. Rivers make up 0.49% of surface freshwater. Although rivers account for only a small amount of freshwater, this is where humans get a large portion of their water from.

Answer:
(1) weight = 565N
distance = 325m
time= 12.6s
power = work done/time
work done= force * distance
= 565*3.25 =1836.25
:. power = 1836.25\12.6
=145.7!
(2) the books will add more to her weight and thereby increasing her power output.
Longitudinal waves have movement in the direction of the wave energy.
