13. a jet taking off from an aircraft carrier goes from 0 to 250 mi/h in 30
a) what is the jet's acceleration?
b) if after take-off, the jet continues to accelerate at the same rate for
15 s, how fast will it be going at that time?
c) how much time does it take for the jet to reach 500 mi/h?
d) how much distance would it take for that same jet to reach 500 mi/hr

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.
