Answer:
I'm assuming you're talking about something like a regular housekey, in which case there are numerous things you can describe!
<u>Its mass:</u> how much it weighs, times the gravity of the system.
<u>Its color:</u> is it silver-colored, or gold, etc.?
<u>Its volume:</u> you could probably calculate this, though it would be hard because it's not a traditional shape, I assume.
<u>Its density:</u> this is mass/volume. It means how many of the atoms are in a given space; how tightly packed the atoms are.
<u>Its tendency to rust / its specific combination of metals or alloys:</u> is it made of copper, tin, steel.. and these are all things that can rust to varying degrees.
A gas can be treated as ideal gas when it is at higher temperatures or low pressures relative to its critical temperature and pressure. Because, at high temperatures and low pressures, the density of gas decreases and at low densities real gases behave as ideal gases.
Answer:
Their positive charge is located in the small nucleus
Explanation:
Ernest Rutherford performed the gold foil experiment in 1911 where he used alpha particles generated from a radioactive source to bombard a thin gold foil.
In his experiment, he observed that the bulk of the alpha particles passed through the gold foil, just a tiny fraction was deflected back. To explain his findings, Rutherford proposed that an atom is made of positively charged centre where nearly all the mass is concentrated called nucleus. Surrounding the nucleus is a large space containing electrons.
Answer:
The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.
