The law of conservation of energy is:
-- Energy can't be created or destroyed.
-- Energy can't just appear out of nowhere. If you suddenly have
more energy, then the 'extra' energy had to come from somewhere.
-- Energy can't just disappear. If you suddenly have less energy,
then the 'missing' energy had to go somewhere.
________________________________________
There are also conservation laws for mass and electric charge.
They say exactly the same thing. Just write 'mass' or 'charge'
in the sentences up above, in place of the word 'energy'.
________________________________________
And now I can tell you that the conservation laws for energy and mass
are actually one single law ... the conservation of mass/energy. That's
because we discovered about 100 years ago that mass can convert
into energy, and energy can convert into mass, and it's the total of BOTH
of them that gets conserved (can't be created or destroyed).
How much mass makes how much energy ?
The answer is E = m c² .

La intensidad de la luz se baja con cada bombillo que agregas
Answer:
1.6 pF
Explanation:
The capacitance of a parallel-plate capacitor in air is given by:
where
is the vacuum permittivity
A is the area of each plate
d is the separation between the plates
In this problem we have:
- Separation between the plates: d = 5.00 mm = 0.005 m
- Area of the plates: 
Therefore, the capacitance is
Answer:
Explanation:
The <em>3N force </em>must be attributed to electrostatic attraction between both charges.
The formula is known as Coulomb's law:
Where:
is the elecrostatic force: 3 N- k is the constant for Coulomb's law ≈ 9.00 × 10⁹ N . m² / C²
- d is the distance that separate the centers of the charges
are the values of the charges: ≈ ± 1.6 × 10⁻¹⁹ C
When you are not interested in the direction of the electrostatic force you just use the magnitudes of the charges.
Substitute in the formula and solve for d:
That can be converted to angstroms with the conversion factor:
