A ball rotates on a string as shown below.
Finger [1]

Answer:

Diagram A

Explanation:

When an object is travelling in a circular path it has an acceleration called centripetal acceleration, even if it is moving with uniform speed. This acceleration is attributed to the object due to change in the direction of velocity at every instant during the motion.

The direction of the velocity of the object is tangent to the circular path at every instant and if the object beaks free of the circular motion, such as breaking of the string, then it will go in the direction tangent to the circle at that instant. Hence, the diagram that best shows the direction ball will travel is:

In ionic bonds what happens to electrons?
OverLord2011 [107]
I think the correct answer from the choices would be that metals donate electrons to nonmetals. Ionic bonding involves transfer of valence electrons. The metal looses its valence electrons which makes it a cation while the nonmetal accepts these electrons.

Answer:

Electron shell

Nucleus

Neutrons

Explanation:

An atom is made up of three fundamental subatomic particles which are the protons, neutrons and electrons.

  • Protons are the positively charged particles. Neutrons do not carry any charges.
  • Both protons and neutrons are found in the tiny nucleus at the center of that atom.
  • The electrons are negatively charged.
  • They are found outside the nucleus in electronic shells.
