Wind resistance is jointly proportional to velocity and surface area of the object. if an object is traveling 67 mph and has a surface area of 8 square feet it will experience a wind resistance of 120.6 newtons. how fast must an object be moving to experience a wind resistance of 45.675 newtons if it has a surface area of 29 square feet? wind resistance is jointly proportional to velocity and surface area of the object. if an object is traveling 67 mph and has a surface area of 8 square feet it will experience a wind resistance of 120.6 newtons. how fast must an object be moving to experience a wind resistance of 45.675 newtons if it has a surface area of 29 square feet?

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.
