(, will give brainliest answer) a 50.0-kilogram skydiver jumps from an airplane and is in freefall for 20 seconds. immediately before she opens her parachute, her kinetic energy is 78,400 joules. if the amount of heat her motion transferred to her surroundings during freefall was 884,000 joules, how far did she fall during her freefall? (assume the skydiver's gravitational potential energy is only transformed into heat and kinetic energy, and assume the rate of acceleration due to earth's gravity is 9.81 m/s/s.) a. 1,960 meters b. 1,560 meters c. 9,620 meters

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.
