The nuclei in the molecule CO (carbon monoxide) are 0.1128 nm apart.  The mass of the most common carbon atom is 1.993 x 10-26 kg, while the mass of the most common oxygen atom is 2.656 x 10-26 kg.  If the energy of the rotating molecule is described by the classical expression

The gap between the valence and conduction bands in diamond is 5.47 eV.  What is the maximum wavelength of a photon that can excite an electron from the top of the valence band into the conduction band?  Express your answer in nanometers.

Which of the following statements are true concerning a good conductor? There may be more than one answer

In which lift would the use of a weight belt be most appropriate and reasonable?

Germanium has a band gap of 0.67 eV. Doping with arsenic adds donor levels in the gap 0.01 eVeV below the bottom of the conduction band. At a temperature of 300 K, the probability is 4.4×10−4 that an electron state is occupied at the bottom of the conduction band.  How far below the bottom of the conduction band is the Fermi level in this case?  Express your answer in eV.

Which of the following best describes bilateral facilitation?

Toxicity is dependent upon the [answer1] and [answer2] dose, as well as the [answer3] and [answer4] of the animal.

Suppose the coefficient of static friction of a horizontal surface is  0 . 388  and the coefficient of kinetic friction of the surface is  0 . 360 . Block A of mass  30 . 0   k g  rests on a horizontal surface (Fig. 2.1), (a) what is the magnitude and direction of the frictional force on the block? If an attached string is parallel to the surface and passes over an ideal pulley, as shown in Fig. 2.2. Block B of mass  3 . 00   k g  is attached to the dangling end of the string, (b) what is the magnitude and direction of the frictional force on block A if it rests on the horizontal surface? If the mass of block B can be changed, (c) what is the mass of block B so that block A is at the verge of motion? If the mass of block B is increased to  16 . 0   k g  (Fig. 2.3), (d) what is the magnitude and direction of the acceleration of block A, and (e) what is the tension on the string? phys1401_final_fig2.jpg
