The solar system moves at the speed of 828,000 km/h. tara writes the following steps to calculate this speed in decameters/second (dm/s). [1 km = 100 dm] step 1: divide 828,000 by 100. step 2: divide the result obtained in step 1 by 60. step 3: divide the result obtained in step 2 by 60. step 4: write the number obtained in step 3 with the unit dm/s. which step is incorrect in the conversion?

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?
