Which chart best shows the relative amounts of potential and kinetic energy
of a roller-coaster car at point E?

Ifound this on google “these two compounds have a different ionic structure. caesium ion is larger in size when compared to the sodium ion. the charge gets more area to spread out evenly. so caesium chloride has a lower melting point than sodium chloride.” i hope this you for what your looking for

Hope the image of the frequency formula

The answer is d.potassium
