A smooth surface hemisphere is fixed on a ground as shown in figure. From the topmost point of it, a small ball starts sliding with no initial velocity. Then the distance s between the center of base circle of hemisphere and the point where particle strikes the ground is

the temperature and the pressure affect solubility. temperature affects by changing the properties of the solvent. the increase in pressure increases solubility, the decrease in pressure decreases solubility.

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.
