Use the graph to answer the question. Two magnets are held apart. Once released, the south pole of one magnet moves toward the north pole of another magnet until the magnets collide. How does the graph reflect the changes in energy that occur? (1 point) Responses The velocity and kinetic energy of the system increase as the energy stored in the magnetic field increases. The velocity and kinetic energy of the system increase as the energy stored in the magnetic field increases. The kinetic energy of the system is derived from the thermal energy created by increased velocity. Energy stored in the magnetic field does not change. The kinetic energy of the system is derived from the thermal energy created by increased velocity. Energy stored in the magnetic field does not change. Kinetic energy and velocity are at zero when the magnets are held apart, and both increase rapidly when they are released and move together. Energy stored in the magnetic field decreases. Kinetic energy and velocity are at zero when the magnets are held apart, and both increase rapidly when they are released and move together. Energy stored in the magnetic field decreases. Kinetic energy is at its peak when the magnets are first released, then it decreases steadily. Energy stored in the magnetic field becomes zero.
Kinetic energy and velocity are at zero when the magnets are held apart, and both increase rapidly when they are released and move together. Energy stored in the magnetic field decreases.
Two magnets are placed on a table, and they immediately move to attach to each other. Which statement is correct about the energies in the system? (1 point) Responses The energy stored in the system is converted to kinetic and thermal energy. The energy stored in the system is converted to kinetic and thermal energy. The energy stored in the system is converted to kinetic, thermal, and sound energy. The energy stored in the system is converted to kinetic, thermal, and sound energy. The energy stored in the system is converted to thermal and sound energy. The energy stored in the system is converted to thermal and sound energy. The energy stored in the system is converted to kinetic energy.
The correct answer is: The energy stored in the system is converted to kinetic and thermal energy.
A magnet is moved close to a rubber band. How does the energy stored in the magnetic field change? (1 point) Responses The energy stored in the magnetic first increases and then decreases. The energy stored in the magnetic first increases and then decreases. The energy stored in the magnetic field increases. The energy stored in the magnetic field increases. The energy stored in the magnetic field does not change. The energy stored in the magnetic field does not change. The energy stored in the magnetic field decreases.
The correct answer is: The energy stored in the magnetic field increases.
Two donut-shaped magnets are stacked on top of each other with a wooden dowel in the center. The south poles of the magnets are facing each other. Once the upper magnet is released, it accelerates downward and stops 1 cm above the lower magnet. How does the energy stored in the magnetic field change? (1 point) Responses Some of the energy stored is converted into kinetic, thermal, and gravitational energy. Some of the energy stored is converted into kinetic, thermal, and gravitational energy. All of the energy stored is converted into kinetic and thermal energy. All of the energy stored is converted into kinetic and thermal energy. All of the energy stored is converted into kinetic, thermal, and gravitational energy. All of the energy stored is converted into kinetic, thermal, and gravitational energy. Some of the energy stored is converted into kinetic and thermal energy.
The correct answer is: All of the energy stored is converted into kinetic and thermal energy.
Which interaction between magnets demonstrates the greatest change in kinetic energy?(1 point) Responses Two small repelling magnets hold each other in place. Two small repelling magnets hold each other in place. Two large repelling magnets hold each other in place. Two large repelling magnets hold each other in place. Two attracting magnets are released while moving away from one another. Two attracting magnets are released while moving away from one another. Two attracting magnets are released while moving towards one another.
The correct answer is: Two attracting magnets are released while moving towards one another.
