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

m then emits two photons: one of wavelength 4052.3 nm to reach an intermediate level and a second to return to the ground state. What was the wavelength of the second photon emitted?

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

frez [133]

MasterCard could use the data warehousing strategy by making its cards acceptable for any transaction in any place.

Data warehouse plays an important role in the competitive market for MasterCard. As the data has been turned into Business Intelligence (BI), which enables individuals, banks and companies to make strong decisions with regard to payment through electronic means.

The data warehousing could be used by MasterCard to gain a distinct advantage over its competitors. As previously Visa represents around 50% of charges for products sold overall while MasterCard was only at 25%.

An example of using Data warehousing is such that banks can issue MasterCard which if used on Aircraft or Restaurants then these banks can use this data to arrange offers and other benefits to motivate cardholders to spend more with their MasterCard. They could even offer limited time openings such as to pay for room or buy exclusive items during shopping.

2. Chico Co. sold $4 million of 10-year bonds on December 31, 2015, with interest payable June 30 and December 31 at an annual r
Aleonysh [2.5K]

Answer:

The requirement of the question is provided below:

a.  What were the proceeds received by Chico upon the sale of the bonds?  

b.  Prepare the entry made by Chico to record the sale of the bonds on December 31, 2015.

The proceeds from the issue is $4,498,488.41

The entries are:

Dr Cash                     $4,498,488.41

Cr Bonds payable                              $4,000,000

Cr Premium on bonds payable           $498,488.41

Explanation:

The first task here is to determine the proceeds from the issue, which can be done using the present value formula in excel.

=pv(rate,nper,pmt,fv)

rate is the effective rate of 10% divided by 2,since coupon is paid twice a year.

nper is the time to maturity of 10 years multiplied by 2

pmt is the coupon payment paid twice a year, that is :12%/2*$4000,000=$240,000

fv is the value expected by investors upon redemption that is $4 million

=-pv(5%,20,240000,4000000)

pv=$4,498,488.41

An investor is given the two investment alternatives (Assets A and B) with the following characteristics: Asset Expected Return
kow [346]

Answer:

12.00%

Explanation:

As per the given question the solution of standard deviation of a portfolio is provided below:-

Standard deviation of a portfolio = √(Standard deviation of Product 1)^2 × (Weight 1)^2 + Standard deviation of Product 2)^2 × (Weight 2)^2 + 2 × Standard deviation of product 1 × Standard deviation of product 2 × Weight 1 × Weight 2 × Correlation

= √(0.165^2 × 0.6^2) + (0.068^2 × 0.4^2) + (2 × 0.6 × 0.4 × 0.165 × 0.068 × 0.7)

= √0.009801  + 0.0007398  + 0.00376992

= √0.01431076

= 0.119628592

or

= 12.00%

So, we have calculated the standard deviation of a portfolio by using the above formula.
