4. Suppose that a system can exist in one of only two energy states, E1 = 2 meV and E2 = 30 meV. An meV (millielectronvolt) is a small unit of energy equal to 1.6 × 10-22 Joules. Suppose that the system is e times (about 2.78 times) as likely to be found in E1 than in E2. Find the temperature of the system, in Kelvin.

Suppose there exist two labour markets — one for low-skilled, and one for high-skilled workers. Any low-skilled worker can become a high-skilled worker by investing in education, the cost of which is c. (a) What, if any, wage gap would exist between low- and high-skilled workers in equilibrium? Explain. (b) Now suppose that an improvement in technology raises the productivity of low-skilled workers. Explain the process by which the markets would adjust to a new equilibrium.

Suppose a simple dye molecule can be modeled as having a hydrogen-like energy states with 6 electrons. Initially, the electrons settle to the lowest total energy state. Imagine that we illuminate this molecule with just right energy to excite the electrons from the n = 3 level to the n = 5 level. When such excited electrons decay back to their lower available energy states, photons of the same energy as the incoming photons are emitted. In addition, photons with...

The law of the conservation of energy states that energy can neither be created or destroyed...

The law of the conservation of energy states that energy can neither be created or destroyed within a closed system, but we also know that any transfer of energy is not 100% efficient and some energy “escapes”. Write briefly about the transfer of energy within our cells …. how do we obtain, store, and use energy? Be sure to give specific examples of the way we convert chemical energy to mechanical and transport/potential energy within the cell. Also address how...

An animal can be in one of two states A or B. An individual in state A will change to state B at an exponential rate α=1； an individual in stat B divides into two new individuals of type A at rate β=2. At the beginning time 0, there is one cell, and it is type A. Estimate the expected number of cells of each type at time 5 and time 10.

Can someone explain to me for E1 mechanism, why OH is the one attacking the hydrogen instead of the conjugate (H2O)? One of the examples that my professor gave me was KOtBu/tBuOH.This one the congugate (tBuOH) is the one attacking the hydrogen instead of the base (KOtBu). I'm confused about if I'm suppose to use the conguate to attack the hydrogen or the base. Please help! He gave me a list of base that will be on the test (NaOH/H2O,...

In the energy level diagram shown below, the energy difference between States 3 and 4 is half the energy difference between states 2 and 3. An electron undergoes a transition (a quantum \"leap\") from State 4 to State 3 resulting in the emission of a photon having a wavelength of 660 nm. (Note: 1 nm = 10-9 m.) What is the frequency the emitted photon resulting from an electron making a transition from State 4 to State 3. f4 to...

Suppose an unknown chemical element has 4 energy levels that its electrons can have and the upper energy levels are 2.5, 4.7, and 5.1 eV above the ground state and the ionization energy of the atoms is 11.5 eV. To answer the question, it helps to draw an energy level diagram for this element. A. If a 5.1 eV photon is absorbed by an electron bound to one of these atoms, in which state was the electron in before it...
