<span>Answer: 124eV
Explanation: Apply Planck - Einstein Relation to calculate the energy of an X-Ray photon that has a frequency of 3.00 x 10^16 Hz and the energy of a photon is proportional to its frequency
E= hv
where E - the energy of the photon
h - Planck's constant, equal to 6.626 x 10^-34 Js
v - the frequency of the photon
and 1 Hz is equal to 1 s^-1
Thus E= 1.988 x 10^-17J
Now convert the energy of photon from joules to eV
Therefore we get 1.988 x 10^-17J x ( 1 eV / 1.6022 x 10^-19 J)
= 124 eV.</span>
Answer:
the rocks have the same amount of thermal energy
The correct answer is: Average Power = 500 W
Explanation:
Root-mean square voltage = Vrms = Vpeak /√2 = 100 / √2 volts
Resistance = R = 10 Ω
Average power = Pavg = (Vrms)^2<span> / R </span>= (100 * 100) / (2 * 10) = <span>500 W</span>
