Answer 1) : The colored and plain sesame seeds represent the subatomic particles neutrons and protons. Explanation :

The attached model of the atom has subatomic particles as neutrons and protons; which are present in the center of the nucleus of the atom. Where neutrons are neutrally charged particles in the nucleus and protons are positively charged particles present in the nucleus of the atom.

Answer 2) The poppy seeds represent the electrons.Explanation :

The poppy seeds used in this atomic model represents the revolving electrons around the the nucleus of the atom in orbits. These are negatively charges subatomic particles which revolves around the nucleus.

The ozone molecule o3 has a permanent dipole moment of 1.8×10−30 cm. although the molecule is very slightly bent-which is why it has a dipole moment-it can be modeled as a uniform rod of length 2.5×10−10 m with the dipole moment perpendicular to the axis of the rod. suppose an ozone molecule is in a 8000 n/c uniform electric field. in equilibrium, the dipole moment is aligned with the electric field. but if the molecule is rotated by a small angle and released, it will oscillate back and forth in simple harmonic motion.what is the frequency f of oscillation?
