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

In a perfectly competitive​ market, all of the following statements are true​ except: A. Marginal revenue is the same as price.
Rashid [163]

Answer: Marginal revenue is equal to price times quantity

Explanation:

A perfectly competitive market is a market where there's a large number of both the producers and the consumers have full and symmetric information.

In a perfectly competitive​ market, the marginal revenue is the same as price and the marginal revenue curve is the same as the demand curve facing sellers.

It should be noted that the statement that the marginal revenue is equal to price times quantity is incorrect. The total revenue is equal to price times quantity.

Bramble Corp. incurs the following costs to produce 13000 units of a subcomponent: Direct materials $10920 Direct labor 14690 Va
Mumz [18]

Answer:

$4,850

Explanation:

The computation is shown below:

Total cost when the production is 13,000 units

Direct materials $10,920

Direct labor $14,690

Variable overhead $16,380

Total $41,900

And, the other case

Their new cost on supplier offer is

= $2.85 × 13,000 units

= $37,050

In the case when the order is accepted So the net income would increased by

= $41,900 - $37,050

= $4,850

Your firm is planning to invest in a new electrostatic power generation system. Electrostat Inc is a firm that specializes in th
kozerog [31]

Answer:

The cost of capital for electrostatic power generators is closest to 7.75%

Explanation:

In order to calculate the estimate of your cost of capital for electrostatic power generators we would have to make the following calculation:

Step-1, Calculation of the Overall Beta

Market Value of Equity = $40,00,00,000 [160,00,000 Shares x $25 per share]

Market Value of Debt = $22,00,00,000

Total Market Value = $62,00,00,000

Therefore, Beta = [Equity Beta x Weight of Equity] + [Debt Beta x Weight of Debt]

= [1.18 x ($40,00,00,000 / $62,00,00,000)] + [0.08 x ($22,00,00,000 / $62,00,00,000)]

= 0.761290 + 0.028387

= 0.789677

Step-2, Cost of capital

As per CAPM Approach, Cost of capital = Risk-free Rate x (Beta x Market Risk Premium)

= 3% + (0.789677 x 6%)

= 3% + 4.75%

= 7.75%

Therefore, the cost of capital for electrostatic power generators is closest to  7.75%
