A group of students performed an experiment to prove the law of conservation of energy. In the experiment, a flask containing water at room temperature was shaken vigorously for a few minutes. The table shows a partial record of the temperature of the water before and after shaking.

Experimental Record
Temperature
Before Shaking 19 °C
After Shaking Unknown

What best predicts the unknown temperature?
Group of answer choices

A. Less than 19 °C, because the total energy of the system after shaking will be lower

B. Greater than 19 °C, because the total energy of the system after shaking will be higher

C. Less than 19 °C, because the energy used for shaking raises the kinetic energy of the water molecules

D. Greater than 19 °C, because the energy used for shaking raises the kinetic energy of the water molecules

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?
