How many photons are absorbed during the dental x-ray?

MariettaO [177]

E=hc/wav. len
E = (6.62 x 10^-34 x 3 x 10^8)/0.0275 x 10^-9
E = 7.22182 x 10^-15 J
To convert to eV divide by 1.6 x 10^-19
E = 7.22182 x 10^-15/1.6 x 10^-19 eV
E =45.36 x 10^3 eV
Th energy, E, of a single x-ray photon in eV is = 45.36keV.

Number of photons, n = total energy/ energy of photon
n = 3.85 x 10^-6/7.22182 x 10^-15
n = 5.33 x 10^8 photons

C. Difference between D) solar energy and fossil fuel energy

jonny [76]

hii

here's your answer

Fossil fuel use is integrated into the fabric of American society. Natural gas, petroleum and coal together accounted for more than 80 percent of energy use in the United States in 2012. Meanwhile, more than 5 gigawatts of solar power capacity was scheduled to come online in 2013 -- about as much capacity as was added for coal plants over a nearly 20-year span. The characteristics of solar power and fossil fuels drive the desire to adopt a particular energy source for a specific application, and they also limit the possible applications of a specific energy source.

A traffic expert wants to estimate the maximum number of cars that can safely travel on a particular road at a given speed. He a

galben [10]

Answer:

Speed s= 19

Explanation:

Take note of the following parameters:

Speed= s,

Number of cars= N,

Number N of cars that can pass a given spot per minute=

N(s)=88s/16+16(s19)2

The principle of differentiation is here:

We let N(s) = N

N = 86s / (17 + 17((s/19)^2))

17N = 86s /(1 + s²/19²)

17N = 361* 86s /(361 + s²)

17N = 31046s /(361 + s²)

Next step;

Differentiate with respect to s

17N = 31046s /(361 + s²)

Remember the quotient rule [u/v]’ = (vu’ - uv’) / v²

Therefore,

u = 31046s =====> du/ds = u’ = 31046

v = (361 + s²) ====>dv/ds = v’ = 2s

17N = 31046s /(361 + s²)

17 dN/ds = ( 31046(361 + s²) - 31046s(2s) ) / (361 + s²)²

The maximum when dN/ds = 0

17 dN/ds = ( 31046(361 + s²) - 31046s(2s) ) / (361 + s²)²

17 * 0 = ( 31046(361 + s²) - 31046s(2s) ) / (361 + s²)²

( 31046(361 + s²) - 31046s(2s) ) = 0

31046 [ (361 + s²) - 2s² ] = 0

31046 (361 - s²) = 0

(361 - s²) = 0

(19 - s)(19 + s) = 0

either s = -19 or s = 19, but s > 0

s = 19

juin [17]

Answer : The correct option is, (C) cannot be reversed

Explanation :

The thermodynamic process is a process in which the thermal or heat energy is converted into mechanical energy and some amount of energy goes into surroundings. That means, the total amount of energy is not converted into mechanical energy.

Or we can say that the energy can not be created or destroyed, it can only change or transfer from one state to another state.

The thermodynamic process is not a reversible process that means it is an irreversible process.

Hence, the correct option is, (C) cannot be reversed
