Answer: Atoms consist of 3 particles: protons, electrons, and neutrons. The nucleus of the atom contains the protons and neutrons. The outer regions contain the electrons
Explanation:
Answer:
600Joules
Explanation:
The energy stored by this battery is calculated using the energy formula;
E = Q× v
Where E is energy
Q is the charge
v is voltage
Hence E = 50 × 12 = 600Joules
Note Q = 12 ampere minute
The correct answer is A. Most reactive non metals.
Firstly if some one knows how to read the periodic table he would have no confusion in deciding whether group 7 has metals or non metals. Group 7 contains non metals so basically we can easily cancel out two options of metals.
Secondly group 7 non metals are the most reactive non metals as they need only one electron in order to complete their valence shell and become stable.
The big bang theory refers to a theoretical concept that explains the creation of our universe. It postulates that the universe started with a giant explosion that created all matter and propelled it outwards in all directions. It is the existence of cosmic background radiation that supports the big bang theory within cosmology.
Answer:
angular frequency of the table must be same as the frequency of the projection of the gum on the wall
Explanation:
Since we know that the projection on the wall is the vertical component of the position of the gum on the rotating table
So here we will say
so the angle made by the radius vector depends on the angular frequency of the disc by which it is rotating
So we can say
so here we can say
so here we can say that
angular frequency of the table must be same as the frequency of the projection of the gum on the wall
