What type of force is responsible for holding molecules together in a solid or liquid?

London dispersion forces

Explanation:

The forces that hold molecules together in the liquid, solid and solution phases are quite weak. They are generally called London dispersion forces. We already know that the electrons in the orbitals of molecules are free to move around.

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
