Weak winds that blow for short periods of time with a short fetch.
Answer:
Electrons.
Explanation:
Electricity was discovered before the discovery of electrons by J.J Thompson in 1896. Before the electron, it was thought that it is the positive ions that move through the wire and carry current—that's why today the conventional current represents the flow of positive charges.
After J.J Thompson's discovery of the electrons, it was realized that it is the electrons that actually carry the current through the conductor. But changing the direction of the conventional current didn't seem appropriate, and that's why the convention continues to be used to this day—reminding us that once it were the positive ions that were thought to carry the current.
No. Force isn't something you can enclose in a box, an envelope,
or a bottle.
A stick of dynamite contains some amount of a chemical compound which,
when triggered by enough heat or shock, undergoes a chemical reaction
that proceeds very rapidly, and generates a large quantity of gases before
the gases can dissipate. This creates very high pressure around the reaction,
and it's this pressure in a small volume that exerts great force for a very short
time. The whole process is often described as an "explosion".
