The specific heat capacity (c) of a substance is the thermal energy required
to raise one gram of the substance by one degree celsius. the total amount
of thermal energy (q) added to a sample of a substance can be calculated
by multiplying the specific heat capacity (c) by the mass of the sample (m)
and the temperature change (t): q c m t. it takes 125 kilojoules (kj)
of energy to heat a cup of water, increasing its temperature by 1°c. what
is the temperature change in °c of the cup of water after 750 kj of energy
are used? s

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?
