Final answer:

The mechanical advantage of a nut cracker is always greater than one, as it allows for a smaller input force to generate a larger output force. The correct option is True.

Step-by-step explanation:

The mechanical advantage of a nut cracker is always greater than one. The mechanical advantage (MA) is defined as the ratio of the output force to the input force. In the case of a nut cracker, when you exert a small input force on the handles, it generates a larger output force to crack the nut. The longer the handles of the nut cracker, the greater the mechanical advantage, as it allows for a larger input force to be exerted.
