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:
- - A up welling is a solution appearing and moving towards the ocean surface meaning as, its going up,
Therefore, C <span>happens when water rises to replace moving surface water</span>
To start with solving this
problem, let us assume a launch angle of 45 degrees since that gives out the
maximum range for given initial speed. Also assuming that it was launched at
ground level since no initial height was given. Using g = 9.8 m/s^2, the
initial velocity is calculated using the formula:
(v sinθ)^2 = (v0 sinθ)^2
– 2 g d
where v is final
velocity = 0 at the peak, v0 is the initial velocity, d is distance = 11 m
Rearranging to find for
v0: <span>
v0 = sqrt (d * g/ sin(2 θ)) </span>
<span>v0 = 10.383 m/s</span>
It's neutral as Cu is +1 and P is -3
