Answer:
Explanation:
The three main particles that make an atom are:
- Proton: its mass is , it carries an electric charge of +e (
), and it is located in the nucles of the atom
- Neutron: its mass is 
, it carries no electric charge, and it is also located in the nucleus of the atom
- Electron: its mass is 
, it carries an electric charge of -e (), and it is located outside the nucleus
The correct answer is:
the distance of the orbiting object to Earth.
In fact, we know that the gravitational force that keeps the object in circular motion around the Earth is equal to the centripetal force, so we can write:
If we re-arrange the equation, we find an expression for the tangential speed of the object:
and we see that it depends on 3 quantities: G, M (the mass of the Earth) and r (the distance of the object from the Earth).
Answer - The given statement is false.

Answer:
Conductors.
Explanation:
Conductors allow the flow of electrons i. e. the current and where some of the electrons energy gets converted into heat while some electrons energy converted into light. Conductors are the materials which has the ability to allow heat and electricity to flow through them. Metals such as gold, copper, Silver, Aluminum, Mercury, Steel, Iron and salty water etc are good conductors of heat and electricity.
