cuz the potential energy is lost  as kinetic energy in the second half....so the entire potential energy is not stored in the rope....
k.e lost=p.e gained and vice versa

Preset resistors are used in circuits when it is necessary to alter the resistance. Dark/light and temperature sensors usually have these components as the preset resistor allows the circuit to be made more or less sensitive
