Aball is rolled twice across the same level laboratory table and allowed to roll off the table and strike the floor. in each trial, the time it takes the ball to travel from the edge of the table to the floor is accurately measured. [neglect friction.] in trial b, the ball is traveling at 5.00 meters per second when it reaches the edge of the table. compare the time it took the ball to reach the floor in trial b to the time it took the ball to reach the floor in trial a

Answer fast for how does the force exerted by two magnets change as the magnets are moved farther apart? the magnetic force increases. the magnetic force decreases. the magnetic force stays the same.

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.

Read through the scenarios below and calculate the predicted change in kinetic energy of the object compared to a 100 kg ball traveling at 5 m/s. a 1,000 kg ball traveling at 5 m/s would have kinetic energy. a 10 kg ball traveling at 5 m/s would have kinetic energy. a 100 kg person falling at 5 m/s would have kinetic energy. the choices for all: the same 10 times more 10 times less 100 times more 100 times less
