Assume that the length of the magnet is much smaller than the separation between it and the charge. As a result of magnetic interaction (i. e., ignore pure Coulomb forces) between the charge and the bar magnet, the magnet will experience which of the following?a) No torque at all
b) A torque only if one magnetic pole is slightly closer to the charge than the other
c) A torque due to the charge attracting the south pole of the magnet
d) A torque due to the charge attracting the north pole of the manget

chemical energy --> gravitational potential energy --> kinetic energy --> elastic potential energy --> gravitational potential energy

explanation:

when emma starts the hike, the chemical energy stored in her body is used to climb up the mountain, and so she gains gravitational potential energy (because at the end, she will be at a higher height h above the ground). then she goes bungee jumping: as she falls, this gravitational potential energy is converted into kinetic energy (because her speed increases as she falls down), until the point when the rope stretches, and she stops moving. at that moment, all the kinetic energy is converted into elastic potential energy due to the stretching of the rope. then, this energy is released because the rope returns to its natural length, and emma gains a small increase in altitude , so she gains some gravitational potential energy.
