The missing question is: how many photons are produced per second?
Answer:
Explanation:
The energy of a photon is given by
where
h is the Planck constant
c is the speed of light
is the wavelength of the photon
In this problem, the photons have wavelength
, so each photon has an energy of
The total energy emitted by the bulb in 1 second is
E = 100 J
Therefore, the number of photons emitted per second is
Explanation:
Extrusive rocks may have a few grains that are large enough to see, but most of them will be too small to see individual minerals. ... The individual mineral grains are almost too small to see. Some extrusive rocks cool so quickly that they do not form any grains. Instead, they form a natural glass.
The forces in some car crashes are greater than others; therefore, the body can be more severely injured by greater and more powerful forces. I hope this helped! :^)
Answer:
if this is a true or false question then it is true.
Explanation:
Answer: No
Explanation:
The force F required is equal to the Force exerted in stretching the first material since conditions are the same
