29.5 g of mercury is heated from 32°c to 161°c, and absorbs 499.2 joules of heat in the process. calculate the specific heat capacity of mercury (in jg°c).

True or false, the three major scales used to measure earthquakes are mercalli scale, richter scale and magnitude scale

Nonpoint source pollution is difficult to control because it

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?
