Chapter 15, Problem 15.56AP
The mass of the deuterium molecule (D2) is twice that of the hydrogen molecule (H2). If the vibrational frequency of H2 is 1.30 × 1014 Hz, what is the vibrational frequency of D2? Assume the “spring constant" of attracting forces is the same for the two molecules.

Carbon-14 (14C) is an unstable isotope of carbon. It has the same chemical properties and electronic structure as the much more abundant isotope carbon-12 (12C), but it has different nuclear properties. Its mass is 14 u, greater than that of carbon-12 because of the two extra neutrons in the carbon-14 nucleus. Assume the CO molecular potential energy is the same for both isotopes of carbon. (a) What is the vibrational frequency of 14CO? (b) What is the moment of inertia of 14CO? (c) What wavelengths of light can be absorbed by 14CO in the (υ = 0, J = 10) state that cause it to end up in the υ = 1 state?
Two blocks of masses m1=1.0 kg and m2=3 kg are connected by an ideal spring of force constant k=4 N/m and relaxed length L. If we make them oscillate horizontally on a frictionless surface, releasing them from rest after stretching the spring, what will be the angular frequency ω of the oscillation? Choose the closest option.
Hint: Find the differential equation for spring deformation.

A cantilever beam in the scanning electron microscope image below is like a diving board, except that it is extremely small (a couple of micrometer). The cantilever beam with mass m can oscillate (imagine a vibrating diving board) and it can be modeled as a spring with a spring constant k. What you can measure experimentally is the frequency of oscillation of the cantilever first without the virus (f1) and after the virus had attached itself to the cantilever (f2). (a) Find the mass of virus from f1 and f2 (assume that we don’t know the spring constant k) (b) Suppose the mass of cantilever is 10.0 * 10^-16 g and a frequency of 2.00 * 10^15 Hz without the virus and 2.87 * 10^14 Hz with the virus.

- In the experiment, you will study an oscillator called a "torsion pendulum." In this case, the restoring "force" is the torsion constant of the wire that suspends the weight X and the inertial term is the rotational inertia of the suspended mass. You will compare the periods of a suspended sphere and of a suspended cube. The rotational inertia of a sphere is Is = 1/10msD^2, where ms is the mass of the sphere and D is its diameter. The rotational inertia of a cube is Ic = 1/6mcS^2, where mc is the mass of the cube and S is the length of its side. If the cube and the sphere are suspended from the same wire, what is the expected ratio of their periods, Tc/Ts? Assume that D = S, ms = 0.20kg, and mc = 0.5 kg.arrow_forwardThe figure below shows a piston from your car engine.
