The energy of a photon is given by

where h is the Planck constant and f is the photon frequency.
We can find the photon's frequency by using the following relationship:

where c is the speed of light and

is the photon's wavelength. By plugging numbers into the equation, we find

And so now we can find the photon energy

We know that 1 Joule corresponds to

So we can convert the photon's energy into electronvolts:
I would say that the answer is 4.) because if she does most of cooking on the stove, that would allow us to make the assumption that she is using heat and therefore requires and apparatus that conducts heat. Copper is also a metallic that is known to be conductive.
The shuttles acceleration in the creases as the fuel is burned because the acceleration of the obect as produced by net force is directly proportional to the magnitude of the net force.
Answer: the thing that brings you life- h2o- idrk the question but if this helps your welcome ^-^have a good day
Explanation:
Answer:
The amount of charge at the center is -132.7 nC
Solution:
As per the question:
Electric flux from one face of cube, 
Edge, a = 19cm
Since, a cube has six faces, thus total flux from all the 6 faces = 
Also, from Gauss' law:
