Answer:
Electrons accelerated to high velocities travel in straight lines through an empty cathode ray tube and strike the glass wall of the tube, causing excited atoms to fluoresce or glow.
Answer:
the ground when the ball hits it
Explanation:
A ball falls freely towards the Earth. If the action force is the Earth pulling down on the ball, then identify which of the following best describe the reaction force:
Explanation:
Chemical bonding results from attractive forces that joins chemical species.
- Noble gases show no tendency to combine with themselves or with other kinds of atoms because of their completely filled outer energy levels.
- The driving force for most interatomic bonding is the tendency to have completely filled outer energy levels just like the inert gases.
- The stable configuration can be attained by losing or gaining of electrons or sharing of pairs of electrons.
Two examples of how bonds form:
Bonds can be formed by:
- Losing and gaining of electrons to form electrovalent or ionic bonds.
- Sharing of electrons to form covalent bonds.

Answer:
Explanation:
Volume of cube=side³
=2*2*2
=8 cm³
Mass of cube=40g
Its density=mass/volume
=5g/cm³
which differs the value given in the text hence it is not gold and u should not bye it...
Instead u should call the police for arresting the person lol...
