Answer:
your question answer is 22°
The easiest way to build a unit for energy is to remember that
'work' is energy, and
Work = (force) x (distance).
So energy is (unit of force) x (unit of distance)
[Energy] = (Newton) (meter) .
'Newton' itself is a combination of base units, so
energy is really
(kilogram-meter/sec²) (meter)
= kilogram-meter² / sec² .
That unit is so complicated that it's been given a special,
shorter name:
Joule .
It doesn't matter what kind of energy you're talking about.
Kinetic, potential, nuclear, electromagnetic, food, chemical,
muscle, wind, solar, steam ... they all boil down to Joules.
And if you generate, use, transfer, or consume 1 Joule of
energy every second, then we say that the 'power' is '1 watt'.
Answer:
F' = 800 N
Explanation:
The electrical force between charges is 400 N.
The electrical force between two charges is given by :
If q₁' = 2q₁, new force becomes,
So, the new force becomes 800 N.
The energy levels of the hydrogen atom are given by
where n is the level number. Let's use this formula to calculate the energy of the levels n=1 (ground state), n=5 and n=6:
- ground state:
- level n=5:
- level n=6:
Now that we have the energy for all the levels we are interested in, we can calculate the energy of the emitted photons.
a) In the first transition, the atom goes from n=6 to n=5. The energy of the emitted photon is equal to the energy difference between these two levels:
The energy of a photon is also equal to
where
h is the Planck constant
c is the speed of light
f is the photon frequency
is its wavelength
Re-arranging this relationship and using the photon's energy, we find its wavelength:
b) in the second transition, from n=5 to n=1, the energy of the emitted photon is equal to the difference in energy between the two levels:
Similarly to part a), the wavelength of the photon is given by:
