As exact conversions, the following information is known: 1 mile = 5280 ft.
12 in. = 1 ft.
3 ft. = 1 yard
1 hr = 60 min
1 day = 24 hr

A particular species of bird can fly for 36.0 hours straight, covering a distance of 158 miles. At this rate, how many feet does the bird travel in 43.0 min?

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?
