A 2.00x10^2-g sample of water at 80.8°C is mixed with 2.00x10^2g of water at 10.0°C Assume that there is no heat loss to the surroundings. What is the final temrperature of the mixture?

An atom's smaller negative particles are at a distance from the central positive particles, so the negative particles are easier to move. 

Wavelength = pie*69+69 with ur mom

The answer is 4f======since electrostatic force is given by    we let f be the electrostatic force when  r = 1 m    if we let  denote the electrostatic force when the distance is decreased so that r = 0.5m, then    we established earlier that f = kq₁q₂. therefore    the force will now be 4f.
