The froghopper (philaenus spumarius), the champion leaper of the insect world, has a mass of 12.3mg and leaves the ground (in the most energetic jumps) at 4.00m/s from a vertical start. the jump itself lasts a mere 1.00ms before the insect is clear of the ground. (a) find the force that the ground exerts on the froghopper during its jump. (b) express the force of (a) in terms of the frog hoppers weight.

2.which choice most accurately explains what happens to the bonds between atoms when water changes to steam, and what becomes of the energy added during this phase change? when water changes to steam bonds between molecules are created. after reaching the boiling point, energy is used to change bond strength and change the kinetic energy of the atoms. when water changes to steam bonds between molecules break apart. after reaching the boiling point, energy is used to break bonds, but does not affect the kinetic energy of the atoms. when water changes to steam bonds between molecules are created. after reaching the boiling point, energy is used to break bonds, but does not affect the kinetic energy of the atoms. when water changes to steam bonds between molecules break apart. after reaching the boiling point, energy is used to change bond strength and change the kinetic energy of the atoms.
