that the magnitude of the electric force between two point charges is directly proportional to the product of the charges and inversely proportional to the square of the distance between them. Coulomb’s law or Coulomb’s inverse-square law is a law of physics describing the electrostatic interaction between electrically charged particles Where Q1 represents the quantity of charge on object 1 (in Coulombs)‚ Q2 represents the quantity of charge on object 2 (in Coulombs)‚ and d represents the distance

electrical force of attraction between two balloons that are charged with the opposite type of charge but the same quantity of charge. The charge on the balloons is 1.2 x 10-8 C and they are separated by a distance of 0.40 m. 2. Determine the electrical force of attraction between two balloons that are charged with the opposite type of charge but the same quantity of charge. The charge on the balloons is 6.5 x 10-7 C and they are separated by a distance of 2.50 m.

roller is covered in silicon tape‚ the lower roller begins to build a negative charge and the belt builds a positive charge. Silicon is more negative than rubber so the lower roller is receiving electrons from the belt when it goes over the roller. The positively charged atomic nuclei‚ try to move toward the negatively charged roller‚ but the belt is in the way. So now the belt gets "coated" with the positive charge‚ which it then carries away from the roller. The belt is positively charged

A. Comparison of Volatility by Rate of Evaporation Volatility describes how easily a substance will vaporize (turn into a gas or vapor). A volatile substance can be defined as (1) a substance that evaporates readily at normal temperatures and/or (2) one that has a measurable vapor pressure. The vapor pressure of a substance is the pressure at which its gaseous (vapor) phase is in equilibrium with its liquid or solid phase. It is a measure of the tendency of molecules and atoms to escape from a liquid
