Which of the following statements is true?
a) If single measurements on identically prepared systems give identical results, the system is in the eigenfunction corresponding to the measured eigenvalue.
b) If a system is in a superposition state, a single measurement on identically prepared systems will always give the same result.
c) If a system is in a superposition state, a single measurement on identically prepared systems will give any one of the possible eigenvalues with equal probability.
d) If a system is in an eigenstate of the operator corresponding to the property being measured, successive measurements on the system will give identical results.

Answer Choices:
B and D
B and C
A and D

Expert Solution

Which of the following statements is true?

a) If single measurements on identically prepared systems give identical results, the system is in the eigenfunction corresponding to the measured eigenvalue. --> Correct, by definition, there is only one eigenfunction ( unique function) if the system is given the same result.

b) If a system is in a superposition state, a single measurement on identically prepared systems will always give the same result. --> False, if they are superpositionated, then there should eb multiple values for the same result, that is, it is not a unique value

c) If a system is in a superposition state, a single measurement on identically prepared systems will give any one of the possible eigenvalues with equal probability. False, will not be with equal probability

d) If a system is in an eigenstate of the operator corresponding to the property being measured, successive measurements on the system will give identical results. True, since it is the eigenfucntion, expect the same predictable values on further calculations

Decide which of the following statements are True and which are False about equilibrium systems: If K = 8 for the reaction A + B ⇌ C + D, K will equal -8 for the reaction C + D ⇌ A + B For a reaction with K >> 1, the rate of the forward reaction is less than the rate of the reverse reaction at equilibrium. The value of K at constant temperature does not depend on the amounts...

Decide which of the following statements are True and which are False about equilibrium systems: The value of K at constant temperature depends on the amounts of reactants and products that are mixed together initially. For a reaction with K >> 1, the rate of the forward reaction is less than the rate of the reverse reaction at equilibrium. A large value of K means the equilibrium position lies far to the left. For the following reaction: CaCO3(s) ⇌ CaO(s)...

Which of the following are true statements about equilibrium systems? For the following reaction at equilibrium: H2(g) + F2(g) ⇌ 2HF(g) removing H2 will have no effect on the amount of F2 present once equilibrium is reestablished. For the following reaction at equilibrium: 2 H2(g) + O2(g) ⇌ 2 H2O(g) the equilibrium will shift to the right if the volume is doubled. Increasing the temperature of an exothermic reaction shifts the equilibrium position to the right. For the following reaction...

Which of the following statements regarding the heat transfer in a PWR are true? The single...

Which of the following statements regarding the heat transfer in a PWR are true? The single phase coolant enters the core with fixed temperature and high pressure (15.5 MPa) and it is heated up by fission heat by about 33 K As the heated-up coolant leaves the core, it is passed into the turbine. The water in the secondary side of the steam generator is heated up by the coolant in the primary loop until boiling

Which one of the following statements is not true about statements of cash flows prepared according to U.S. GAAP?

Which one of the following statements is not true about statements of cash flows prepared according to U.S. GAAP? The operating section of the indirect method starts with the net income of the period. In the indirect method statement, the period's depreciation is added to net income because it is a source of cash. Interest payments are included in the operating section of the direct method statement. The investing section of the direct method statement for a period is identical to the investing section...
