Answer:
The separation between the two lowest levels = 
The values of n where the energy of molecule reaches 1/2 kT at 300K = 
The separation at this level = 1.8 *
J
Explanation:
Knowing the formula
En = 
Mass of oxygen molecule
m (O2) = 32 amu * 
So the energy diference between the two lowest levels:
E2 - E1 = 
E2 - E1 = 
Now we should find n where the energy of molecule reaches 1/2 kT
En =
= 
= 


by the end is necessary to calculate the separation of the level
En - En-1 = 
= 1.8 *
J
Answer: reliable
Explanation:
Reliable (marketing research) information is collected from questions (measurements) that are free from systematic or statistical error. An absence of systematic error implies that the respondents (i.e., the sampled people) who answer questions actually understand what the questions were asking.

Answer:
Explanation:
The two major defects of simple electric cells causes current supplied to be for short time. These defects are: polarization and local action.
a. Polarization: This is a defect caused by an accumulation of hydrogen bubbles at the positive electrode of the cell. It can be prevented by the use of vent, using a hydrogen absorbing material or the use of a depolarizer.
b. Local Action: This is the gradual wearing away of the electrode due to impurities in the zinc plate. It can be controlled by the amalgamation of the zinc plate before it is used.
