Daryl is conducting experiments on samples of pure copper (Cu). While collecting data, he records both the physical and chemical properties of the metal. Which of the following is dependent on the amount of copper particles in the sample? A)Electrical conductivity. B)Thermal conductivity. C)Mass. D)Density

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?
