Human activities add carbon to Earth’s atmosphere at a rate of about 1,000 million metric tons per year. As part of the natural carbon cycle, land plants and the ocean remove about 55% of this extra carbon and about 45% stays in the atmosphere. Identify TWO Earth systems that are being affected by the extra carbon from human activities. Explain how each Earth system is being affected.

Which of the following has wavelength longer than the wavelength of viable light? a) x rays b) gamma rays c) radios waves d) ultraviolet waves

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?
