Answer:
It's called the working distance
.
Answer:
i believe it's the last one
Explanation:
because the first law of thermodynamics states that energy can be changed from one form to another, but it cannot be created or destroyed.
good luck :)
i hope this helps
have a great day !!
Because sometimes it happens that they discover a dwarf planet
that nobody ever knew about before. When that happens, they
ADD the new one to the list of known dwarf planets, and then the
total number of dwarf planets on the list increases by 1 .
The electrostatic force between two charged object is given by:
where
k is the Coulomb's constant
q1 and q2 are the charges of the two objects
r is the separation between the two objects
We see that the force is inversely proportional to the square of the distance:
. Therefore, if the distance is doubled, the force decreases by a factor 4, and the new force will be:
and it will still be a repulsive force, since the two balloons have charges of same sign.
Nuclear energy is the stored potential energy in the nucleus of an atom. This form of energy is released either when unstable nucleus splits into smaller nuclei , known as fission, or when nuclei fuse together, a process known as fusion. Compared to this, light energy is a form of electromagnetic radiation such that it is composed of photons, which are small packets of light energy. Each photon has a characteristic wavelength, frequency, etc. Light energy has photons which have no mass whereas nuclear energy comes from nucleus, and involves mass.
