Answer:

D

Explanation:

The formula for calculating kinetic energy is 1/2mv^2, where m is the mass and v is the velocity or speed of the object. Since all of the balls have the same mass, the one with the highest speed or velocity will have the highest kinetic energy. Hope this helps!

Which group/family contains elements with the smallest radius within the same period?
nasty-shy [4]

Answer:

Halogens

Explanation:

From the given choices, the halogens will have the smallest radius within the same period.

The size of an atom is estimated by the atomic radius. This is taken as half of the inter-nuclear distance between two covalently bonded atoms of non-metallic elements or half of the distance between two nuclei in the solid state.

  • Across a period in the periodic table, atomic radii decrease progressively from left to right.
  • Down a group from top to bottom, atomic radii increase progressively due to the addition of successive shells.

Since halogen is the right most group from the choices given, it will have the smallest radius.
