Answer:
Explanation:
Electrostatic Forces
The force exerted between two point charges 
and 
separated a distance d is given by Coulomb's formula
The forces are attractive if the charges have different signs and repulsive if they have equal signs.
The problem described in the question locates three point charges in a straight line. The charges have the values shown below
The distance between 
and is
The distance between and is
We must find the value of such that
Applying Coulomb's formula for is
Now for
If the total force on is zero, both forces must be equal. Note that being q2 negative, the force on q3 is to the right. The force exerted by q1 must go to the left, thus q1 must be positive. Equating the forces we have:
Simplfying and solving for
Use the density formula:
Mass of the substance
————————————
Volume of the substance
This gives you the density.
Corn syrup has a density of about 1.4 grams per cubic centimeter, and has the highest density of all liquids!
Hope this helps!
It mainly travels by kinetic energy
Ionic compounds is your answer. What happens is one atom donates electron(s) to the other atom, making one positive and the other negative. The opposite atoms attract, forming an ionic bond.
