Objects 1 and 2 attract each other with a electrostatic force of 72.0 units. if the charge of object 1 is doubled and the distance separating objects 1 and 2 is doubled , then the net electrostatic force will be ?

The electronic structure or chlorine is 2.8.7 what is the electronic structure of fluorine?

Amass attached to a spring is displaced from its equilibrium position by 5cm and released. the system then oscillates in simple harmonic motion with a period of 1s. if that same mass–spring system is displaced from equilibrium by 10cm instead, what will its period be in this case? a mass attached to a spring is displaced from its equilibrium position by and released. the system then oscillates in simple harmonic motion with a period of . if that same mass–spring system is displaced from equilibrium by instead, what will its period be in this case? a) 0.5sb) 2sc) 1sd) 1.4s

Since the energy was not raising the temperature of the water during these segments, what was the energy used to do instead? your answer must include an explanation of what is happening to the molecules.
