Answer:
Explanation:
The force between charges, 
Positive charge, 
Negative charge, 
We need to find the distance between charges. The force of attraction between charges is given by :
Where
r is the distance between charges
So, the distance between charges is 
.
Answer:
A. The particles will begin to move enough
that they slide past each other.
Explanation:
When the plastic cup is heated, the Kinetic energy of its particles starts increasing. As the temperature rises, the kinetic energy keeps increasing. With the increase of K.E, the particles start moving faster and faster. When the temperature finally reaches the melting point, the K.E of the molecules is enough to break the bonds and slide past each other.
