Consider the first overtone vibrational band of the 11b19f molecule within the harmonic oscillator, rigid-rotor approximation. the harmonic vibrational frequency and rotational constant of this isotopomer are equal to 1402.13 cm-1 and 1.50724 cm-1 , respectively. determine the frequency (in cm-1 ) of the j = 5 → 6 r-branch transition in the 1-st overtone. what gives rise to vibrational overtones?

d they tend to lose electrons and become cations.

explanation:

i think the answer is a, hope this is right, that would be my best guess.

answer: at 24 february, 2014 the population gets twice of its initial population.

explanation:

since we have given that

the population for alpha city, t years after january 1, 2004 is given as

first we find out the initial population, i.e. t=0,

so, our quadratic equation becomes,

according to question, we have said that if the population has twice its initial population, then it becomes

so, time taken to reach this above mentioned population is given by

now, we know that time can't be negative so, we take t=9.149 years.

hence, at 24 february, 2014 the population gets twice of its initial population.

electric field is a function of 1/r^2

yes, the force per unit charge for a point charge is inverse square law.
