You work for a company that produces ultra-absorbent diapers. Suppose you added water to five different polymers (materials) and want to choose the best one for your diapers. Which of the following would you choose? the polymer with the least hydrated mass
the polymer with the greatest hydrated mass
the polymer with the smallest difference between the initial and final masses
the polymer with the greatest difference between the initial and final masses

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?
