Power source (battery/energy) a copper/metal wire, and then a receiver
The question is incomplete, the complete question is;
The lightest particle among the following is:
• Electron •Proton • Neutron • Alpha
Answer:
Electron
Explanation:
There three basic subatomic particles are electrons, protons and neutrons. Both protons and neutrons are found in the nuclear and both contribute towards the mass of the atom. The alpha particle has the same mass as the helium nucleus.
However, the electrons are found in orbiit and have a negligible mass compared to the mass of the protons and neutrons. The mass of the electron is about 9.11 × 10^-31 Kg. This makes it the lightest of all the particles listed among the options.
I only know #8 and the raindrop would increase speed due to gravity.
It is also a compound<span> because the atoms that make water are </span>not<span> all the same - some are oxygen and some are hydrogen. Oxygen in the atmosphere is a molecule because it is made from two atoms of oxygen. It is </span>not a compound<span> because it is made from atoms of only one element - oxygen.</span>
Explanation:
Elements heavier than Helium are synthesized in a number of environments. For elements that are lighter than Iron, those elements are synthesized during various phases in the evolution of massive stars. For elements heavier than Iron, one needs quite a bit of energy input to form these heavy elements.
