13. A ground state hydrogen atom absorbs a photon of wavelength 94.98 nm and its electron attains a higher energy level. The ato

barxatty [35]

Answer:

wavelength of the second photon emitted is 97.26 nm

Explanation:

Data provided;

Wavelength absorbed = 94.98 nm

Wavelength of the one of the emitted photon = 4052.3 nm

Now,

The energy is given as:

Energy = $\frac{\textup{hc}}{\lambda}$

here,

h is the plank's constant

c is the speed of the light

λ is the wavelength

Now,

by the principle of conservation of energy

Initial energy = Final energy

Therefore,

$\frac{\textup{hc}}{94.98}$ = $\frac{\textup{hc}}{4052.3}$ + $\frac{\textup{hc}}{\lambda_1}$

or

$\frac{\textup{hc}}{\lambda_1}$ = $\frac{\textup{hc}}{94.98}$ - $\frac{\textup{hc}}{4052.3}$

or

$\frac{\textup{1}}{\lambda_1}$ = $\frac{\textup{1}}{94.98}$ - $\frac{\textup{1}}{4052.3}$

or

$\frac{\textup{1}}{\lambda_1}$ = 0.0105 - 2.46 × 10⁻⁴

or

$\frac{\textup{1}}{\lambda_1}$ = 0.01028

or

λ₁ = 97.26 nm

Hence,

the wavelength of the second photon emitted is 97.26 nm

The consumer price index for Planet Econ consists of only two items: books andhamburgers. In 2010, the base year, the typical co

Stels [109]

Answer:

The consumer price index for 2015 on Planet Econ is 1.25

Explanation:

The formula for computing the consumer price index is given below:

= (Total cost in the current year) ÷ (total cost in the base year)

where,

Total cost in the current year equals to

= (Base year book quantity × current year book price) + (base year hamburgers quantity × current year hamburgers price)

= 10 books × $30 + 25 hamburgers × $3

= $300 + $75

= $375

we use the base year quantity for computing the total cost for the current year.

And, the Total cost in the base year equals to

= (Base year book quantity × base year book price) + (base year hamburgers quantity × base year hamburgers price)

= 10 books × $25 + 25 hamburgers × $2

= $250 + $50

= $300

Now put these values to the above formula

So, the answer would be

= $375 ÷ $300

= 1.25

Hence, The consumer price index for 2015 on Planet Econ is 1.25

Universal Travel Inc borrowed $500,000 on November 1, 2018 and signed a twelve month note bearing interest at 6% Principal and i

horrorfan [7]

Answer:

Interest will be $5000

So option (A) will be correct option

Explanation:

We have given principal amount P = $500000

Rate of interest = 6 %

Time is November 1 to December 31

So time = 2 months = 0.1666 year

Interest is given by

Interest $=\frac{principal\ amount\times rate\times time}{100}=\frac{500000\times 6\times 0.1666}{100}=$5000$

So option (a) will be correct option

Renaldo Cross Company views share buybacks as treasury stock. Renaldo repurchased shares and then later sold the shares at more

allsm [11]

Answer: a) Option A

Explanation:

There will be no effect on retained earnings because retained earnings do not increase as a result of shares being sold. It increases when net income increases.

Total paid-in capital increases when stock is sold for higher than its par value or when treasury stock is sold for higher than its acquisition price. The treasury stock here was sold for higher than it was bought so this would increase the total paid in capital.
