Final answer:
The question is asking for an example of a device that does not involve an energy transformation. All options provided involve energy transformations.
Step-by-step explanation:
The question is asking for an example of a device that does not involve an energy transformation. An energy transformation refers to the conversion of one form of energy into another form. In this case, all of the options given involve energy transformations.
a. ATM machine: When money is dispensed from an ATM, electrical energy is converted into mechanical energy to dispense the cash.
b. Grocery self-checkout: In a self-checkout machine, electrical energy is converted into mechanical energy to move the conveyor belt and scan items.
c. Airport ticket machine: When a ticket is printed, electrical energy is converted into thermal energy to produce the heat needed for printing.
d. Restaurant ordering machine: When an order is placed, electrical energy is converted into sound energy as the machine produces a voice recording or generates an alert.
Therefore, the answer is e. None of the above as all the options involve energy transformations.
